  • Patent number: 5993530
    Abstract: A thermally-decomposable, biodegradable resin composition is dispersed and stabilized in water optionally along with additives to give an aqueous dispersion of the resin composition. In the dispersion, the base polymer consists substantially of a water-insoluble starch-type, biodegradable resin. The dispersion is usable in various fields of papermaking, non-woven fabric production, film and sheet production and woven fabric production, in those of dispersed adhesive production, and in those of metal processing, plastic processing, wood processing and stone processing.

  • Patent number: 5976000
    Abstract: A hard polishing pad with a porous surface for use in chemical-mechanical planarization of semiconductor wafers. The polishing pad has a body with a planarizing surface upon which a slurry may be deposited, and a plurality of particles are suspended in the body. The body is made from a continuous phase matrix material, and the particles are made from a substantially incompressible material that is soluble in the slurry. As a wafer is planarized, the particles at the planarizing surface of the polishing pad dissolve in the slurry and create pores in the pad. Also, because the particles are substantially incompressible, they reinforce the pad to provide a hard, substantially incompressible pad.

  • Patent number: 5922119
    Abstract: The invention is directed to the use of an aqueous protective coating composition containing a binder system and an associative thickener for industrial coatings. The associative thickener is not a polyurethane thickener and is selected so that its concentration required by the specific application method is below the critical concentration C*, defined as the thickener concentration at which the coils of the thickener polymer start to overlap of entangle calculated according to the Mark Houwink equation.

  • Patent number: 5902392
    Abstract: This invention involves a novel paint formulation comprising a phosphate or metal sulfide heavy metal reactive compound, a binder, a solubilizing compound and a buffer which acts as a carrier for heavy metal reactive chemicals so that when this novel paint is applied to a heavy metal painted surface and both are subsequently removed, the heavy metal paint waste is rendered non-hazardous under the TCLP test.

  • Patent number: 5879440
    Abstract: Water-borne paints containing reduced molecular weight polysaccharide derivatives that are resistant to enzyme hydrolysis. The water-borne paints are biostable, retaining at least about 80% of their initial viscosity 24 hours after they are inoculated with polysaccharide hydrolysis enzyme. A process for making the biostable water-borne paints has the steps: a) treating precursor polysaccharide derivative with polysaccharide hydrolysis enzyme in aqueous medium for a time sufficient to obtain reduced molecular weight polysaccharide derivative; and b) mixing the reduced molecular weight polysaccharide derivative with an effective amount of at least one other water-borne paint ingredient to obtain a water-borne paint.

  • Patent number: 5844023
    Abstract: A biologically degradable polymer mixture is proposed which consists essentially of starch and at least one hydrophobic polymer. The hydrophobic polymer is in this connection at least substantially biologically degradable and thermoplastically processable and the mixture with the starch comprising a polymer phase mediator or a macromolecular dispersing agent so that the starch is present in the mixture as disperse phase with the hydrophobic polymer as continuous phase, and the phase mediator or the dispersing agent is responsible for the molecular coupling of the two phases. As starch there is preferably used thermoplastic starch which has been prepared substantially with the exclusion of water by means of sorbitol or glycerol. The production of the biologically degradable polymer mixture is also carried out substantially with the exclusion of water.

  • Patent number: 5801220
    Abstract: A rapid disintegrating and dispersing composition for thickening liquid waste into a thixotropic gel comprises a polymeric acrylic resin and a colloid-forming mixture of microcrystalline cellulose and sodium carboxymethylcellulose. Additional ingredients preferably used in making a tableted form of the composition include microcrystalline cellulose per se, polyvinylpolypyrrolidone, magnesium stearate and amorphous silica. The tablet is placed in suitable containment means such as a containment bag. The thixotropic properties of the composition enable the gelled waste to be restored to a liquid when small amounts of hand pressure are applied to the waste containment bag, thereby providing a convenient and simple means for disposal.

  • Patent number: 5744520
    Abstract: A process for the preparation of polymer compositions which comprises mixing a conductive component with an anionic polymeric latex containing a polymer; adding a cationic surfactant, or flocculant whereby the aggregation of the latex particles and the conductive component particles results; subsequently adding colloidal stabilizer, followed by the addition of a base to obtain a pH of from about 7 to about 12; heating above about the polymer glass transition temperature thereby enabling the severage, or breakage of the formed aggregated particles; further heating above about the polymer glass transition temperature enabling the coalescence of the polymer and conductive component particles; and optionally washing and drying the resulting coalesced product.

  • Patent number: 5710195
    Abstract: This invention applies to methods for creating opaque indicia on substrate surfaces and to non-pigmented, moisture-free, jet ink compositions containing only solvents and solvent soluble resins and dyes that exhibit the acceptable characteristics of opacity, contrast, adhesion and machine compatibility. The compositions are on weight percentage basis as stated below. The compositions contain a combination of film forming resins of varying molecular weights of a dry resin solids percentage between 8 and 15%. The resins are chosen from the following: nitrates of cellulose; acrylics; alkyds; vinyl acetate-vinyl chloride copolymers; and styrene acrylic. The quantities of resin are chosen according to the desired viscosity, adhesion strength of film on the subject substrate and the degree of shearing of the drying resin mixture. An optimum balance of adhesion and opacity is stoichiometrically obtained.
