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.
