Abstract: It is known that polyurethane hydrolyzes in superheated steam.The oily hydrolyzate from a polyurethane derived from a polyether diol is filtered and stripped to remove the water and remove any unhydrolyzed water-insoluble polymer such as vulcanized rubber, etc. that may be present. There may be a substantial amount of scrap rubber present in the scrap polyurethane that is treated, such as the scrap from a plant producing rubber and plastic products, or scrap articles that may include rubber and polyurethane, such as mats, cushions, automobile parts, solid and pneumatic tires, etc., or scrap which contains old rubber and polyurethane products such as an accululation of scrap rubber tires and polyurethane tires, etc.

Abstract: The composition comprises an aqueous mixture of an acrylic acid ester copolymer and/or a polyvinyl ether; polyvinyl methyl ether; an alkali metal and/or ammonium salt of polyacrylic acid, of polymethacrylic acid or of copolymer of acrylic and methacrylic acids; a monomeric plasticizer; and an emulsifier. The composition is useful as a pressure sensitive adhesive for labels. A label coated with the composition is readily removed from the surface upon which it is affixed by treatment with water.
Abstract: In reclaiming thermoplastic materials, process improvements wherein ground particles having molecular orientation are heated sufficiently to relieve orientation stresses and reduce surface area, thereby facilitating subsequent washing, separating and melt processing steps. When refabrication into other articles is intended, the materials can be exposed to a hot caustic solution to eliminate bacteria and mold growth.
Abstract: Linear, thermoplastic polyesters formed from certain s-triazinedicarboxylic acids, N-heterocyclic diols, and, if appropriate, alkanediols. The polyesters are thermoplastic materials from which moulded materials having valuable thermo-mechanical properties can be manufactured by the customary shaping processes, such as casting, injection moulding and extrusion. They are suitable for use as engineering plastic materials and for coating objects.
Abstract: Lactam-polyol-polyacyl lactam or lactam-polyol-acyl polylactam terpolymers having up to 100% ester end group termination, and both ester linkages and amide linkages between the monomeric segments are disclosed. Also disclosed is a process for preparing the above terpolymer comprising reacting together a lactam, polyol, polyacyl lactam or acyl polylactam, and an alcohol in the presence of a basic lactam polymerization catalyst.
Abstract: Linear, thermoplastic copolyesters based on terephthalic acid and/or isophthalic, s-triazinedicarboxylic acid derivative, alkanediols and/or N-heterocyclic diols. The copolyesters are thermoplastics materials from which moulded materials having valuable thermo-mechanical properties can be manufactured by the customary shaping processes such as casting, injection moulding and extrusion. They are suitable for use as engineering plastic materials and for coating objects.
Abstract: Block copolymers can be prepared by reacting a polyester resin or a polyol with a hydroxyl or carboxyl functional mercaptan and subsequently reacting the mercapto-blocked polyester or polyol in the presence of peroxygen-type or azo-type catalyst, with selected alpha, beta-ethylenically unsaturated monomer(s), such as diacetone acrylamide, acrylic acid, methacrylic acid, ethyl acrylate, butyl acrylate, styrene, methyl methacrylate, methacrylonitrile and the like. Such block copolymers provide for coating compositions having physical properties which provide for useful protective and decorative films.

Abstract: Vulcanizable elastomeric compositions are disclosed which are the reaction products of 80 to 90 mole percent of a mixture of thiodiethanol and one or more aliphatic or cycloaliphatic diols and 20 to 10 mole percent of an aromatic or cycloaliphatic dicarboxylic acid wherein the diol content is at least 50 mole percent thiodiethanol and about 1 to 10 mole percent of a diol providing pendant allylic unsaturation.
Abstract: The disclosure relates to a process for recovering from waste polymer from the wash down of reactors after the polymerization of styrene and butadiene to produce useful elastomeric products. The process comprises compounding the waste polymer on a two roll rubber mill with a chlorinated petroleum wax and a sulfamic acid gel (sulfamic acid is also known as a amidosulfonic acid) and compounding the same at certain selected temperatures for a period of time to produce a usable copolymeric elastomeric product.
Abstract: The heat distortion resistance and the molecular weight of polypropylene terephthalate and polybentylene terephthalate can be increased by cocondensing up to 10 mol-% of aliphatic diols containing 5 to 10 carbon atoms or of cycloaliphatic diols containing 8 to 12 carbon atoms.

Abstract: Unsaturated, linear polyesters having flame-retarding properties are obtained by polycondensing unsaturated dicarboxylic acids, optionally mixed with aromatic dicarboxylic acids and aliphatic diols, with brominated and/or chlorinated 1,3-di-(hydroxyalkyl)-benzimidazolone compounds. The new, unsaturated polyesters can be polymerized easily, also when mixed with other polymerizable monomers, and give moulding materials having flame-retarding properties.
