Abstract: A plastic laminate sheet for making collapsible dispensing container comprises an outer layer of filled-plastic made of polypropylene or a blend of polypropylene, and high density polyethylene, and a filler, preferably calcium carbonate, incorporated therein. The outer filled-plastic layer is coextensively bonded to an inner layer of high density polyethylene to form the laminate sheet. An intermediate layer of an oxygen barrier plastic may be interposed in the laminate sheet in order to impart oxygen impermeability thereto.

Abstract: A method is provided for making certain methoxy-substituted silyl benzophenones useful as ultraviolet light absorbing agents for silicone hardcoat formulations. The methoxy-substituted benzophenones have been found to more readily equilibrate into silicone hardcoat formulations without adversely affecting the shelf-life of the resulting formulation. The ultraviolet light absorbing agents are obtained by equilibrating a mixture of methanol and trialkoxysilyl-substituted benzophenone in the presence of an acid catalyst. The resulting UV stabilized silicon hardcoat formulations also provide silicone hardcoated plastic articles having improved thermoformability, resistance to abrasion, and environmental degradation.

Abstract: A copper plastic laminate is provided having a high bond strength. The copper is selected from the group consisting of copper and copper alloys and has on its surface a uniform glassy-like, substantially pore-free coating of copper phosphate. A plastic encapsulating material containing a mold release agent is adhesively bonded to the copper.

Abstract: A coating for ship hulls is designed for application to areas of the hull t accessible when ship is in dry dock. The means for applying the coating may take several forms: (1) a multilayered tape system having impregnated in or carrying an antifoulant and having a water soluble intermediate layer; (2) a sponge like layer containing impregnated antifoulant paint or coating liquid which can be squeezed therefrom onto the hull; (3) a sponge having mixed therein microspheres of resin and pigment and microspheres of activator material such that when the microspheres are crushed, the pigmented resin, which may also contain an antifoulant, and the activator are mixed and cured to form a coating on the hull. The preferred means and method for applying the coating, is to mount the tape system on the dock blocks in a dry dock before the dry dock is flooded to admit the ship, and by the settling then activate the coating the ship onto the blocks as the water is withdrawn from the dry dock.

Abstract: A linerless double-coated pressure-sensitive adhesive tape of the prior art is wound directly upon itself into a roll that can later be unwound without delamination or offsetting of adhesive. The novel tape differs from the prior tape in that the pressure-sensitive adhesive at each of its faces is a substantially solvent-free, crosslinked alkyl acrylate polymer and can be aggressively tacky for uses requiring high-performance adhesion.

Abstract: A copper plastic laminate is provided having a high bond strength. The copper is selected from the group consisting of copper and copper alloys and has on its surface a uniform glassy-like, substantially pore-free coating of copper phosphate. A plastic encapsulating material containing a mold release agent is adhesively bonded to the copper.

Abstract: A flame-retarded copper-clad laminate is provided comprising a plurality of paper substrate layers each impregnated with an unsaturated polyester resin and a copper cladding adhesively bonded onto at least one side thereof.The improvement comprises said unsaturated polyester resin containing an aliphatic and/or alicyclic brominated flame-retardant and aromatic brominated flame-retardant in combination.

Abstract: An article comprising a backing, a silicone pressure sensitive adhesive, and optionally, a silicone release coating is provided for effecting removal of vertically cohesive inks from cellulosic materials. There is also provided the process of making and using the article.

Abstract: A fiber-cement/plywood surface and method of providing a preformed surface material for flooring, decking, walkways and roadways, more particularly for use with marine dock structures. The method includes applying a coating of a polyester resin over one surface of a sheet of plywood substructure so as to seal the substructure as the resin hardens, and also coating one surface of a fiber-cement sheet with a polyester resin and allowing it to harden. A bonding agent, which comprises a catalyzed polyester resin mixed with a thickening agent such as mill fibers or finely chopped fiberglass strands, is applied between the two facing resin surfaces of the respective plywood sheet and the fiber-cement sheet, whereby the two sheets are bonded together so as to form a single somewhat-resilient weatherproof and wear-resistant structure or panel. An alternative arrangement is also provided wherein the substructure is a thick plastic foam core encased in a fiberglass and polyester resin.

Abstract: A multilayer plastic film suitable for use in the manufacture of garbage and trash bags wherein the film comprises at least one layer of a high pressure low density polyethylene, and a layer comprising low pressure low density gas phase heterogeneous copolymers formed from ethylene, and at least one of propylene and butene-1 and at least one C.sub.5 -C.sub.8 comonomer.

Abstract: Composite of two pressure-sensitive adhesive tapes which are releasably adhered together adhesive face to adhesive face and then put to individual uses. The tapes are separable because their facing adhesives are substantially solvent-free, crosslinked alkyl acrylate polymers which can be aggressively tacky for uses requiring high-performance adhesion.

Abstract: A laminate providing an effective barrier to the migration of essential oils and/or flavorings, such as d-limonene, therethrough is provided comprising, from the outer surface to the inner surface, a paperboard substrate, a web of propylene polymer coated thereon and a web of olefin polymer overlying said propylene polymer web. Preferably the paperboard substrate is also coated on the external surface thereof with a web of heat sealable olefin polymer. Containers constructed from such laminates are especially useful as fruit juice containers which enable significant flavor retention in the fruit juice contained therein over the normal shelf life of the product.

Abstract: The invention encompasses a petrolatum wax-biocidal composition and a method of preserving wood with the composition.

Abstract: A multilayer film suitable for use in the manufacture of garbage and trash bags wherein the first outer layer comprises a blend of a low pressure, low density polyethylene having a melt index of about 1 decigram per minute and a low pressure, low density polyethylene having a melt index of about 2 decigrams per minute. The second outer layer is made with a high pressure, low density polyethylene.

Abstract: The present invention relates to heat sealable laminar thermoplastic films which may be heat sealed over a wide range of temperatures. The resultant heat seals exhibit a high heat seal strength. Such laminar structures comprise at least two layers of thermoplastic film, one of the layers being an oriented base layer and the other layer a heat sealable skin layer. Preferably the base layer is an alpha olefin such as polypropylene or copolymers thereof and the skin layer is preferably a linear, low-density polyethylene copolymer, comprising ethylene which has been copolymerized with another alpha olefin in the presence of a stereospecific catalyst.

Abstract: An aluminum atom- and monocarboxylic acid residue-containing polyester is provided.

Abstract: Described herein are laminate compositions comprising a polyarylate, or blends thereof, derived from a dihydric phenol and an aromatic dicarboxylic acid which is laminated upon the surface of a poly(aryl ether), particularly polysulfone. In contrast to the highly ultraviolet sensitive polysulfone, the laminate compositions of this invention exhibit good weatherability including no adverse effects, e.g., degradation, from prolonged ultraviolet irradiation exposure. The laminate compositions of this invention have beneficial utility in solar energy applications.
