摘要： There is provided a polyurethane ground rubber composite and a new method for formation and preparation thereof. The composite is suitable for use in laminated and other surfacing or as a surfacing and has excellent flexibility, resiliency, weatherability, and elastomeric qualities; and comprises particulate vulcanized rubber substantially coated on each particle with about 3 to about 8 microns, and in some instances about 3 to about 10 microns, of a cross-linked binder derived from an essentially solvent-free polymeric isocyanate prepolymer having a number average molecular weight of 800-4000, the cross-linking of the isocyanate prepolymer being accomplished by controlled reaction with water using an equivalent ratio of NCO/OH of 0.14/1 to 0.83/1 to form urea and buiret linkages, and providing a void content of 25-60 volume percent, so that the carbon dioxide generated by the water/isocyanate reaction can readily diffuse through the film and so that the vented carbon dioxide does not cause foaming of the composite; and methods of controlling the forming of the composite, the layering of the composite, and/or mixing it in situ.

摘要： A method of backing carpeting material 19 with hot-melt compositions such as atactic polypropylene or bitumen comprises carefully doctoring selected thicknesses of the composition to the undersurface of the material 19 with the wear surface of the material uppermost. In one arrangement this is achieved using a lick roll arrangement 20 incorporating a doctor blade, cooling the backed product at cooling zones 28, 29 and applying the material to a nip formed by rollers 21. In another arrangement this is achieved by doctor box 16 applying the composition to a carrier 13, the carpeting material 19 then being laminated at roll 21 to the layer of composition, the laminate then being cooled before being stripped from the carrier 13. In a further arrangement the carrier is in the form of sheet material 15 which is supported by endless belt 13 and which is bonded into the hot-melt composition to become an integral part thereof.

摘要： A process for the production of synthetic rubber latices by the emulsion polymerization of a monomer mixture of:40 to 80 parts by weight of a conjugated diene;0 to 45 parts by weight of an aromatic vinyl compound;0 to 30 parts by weight of (meth)acrylonitrile0 to 30 parts by weight of a (meth)acrylic acid ester containing from 1 to 12 carbon atoms in the alcohol component or other copolymerizable compounds, and0.5 to 5.0 parts by weight of an .alpha., .beta.-unsaturated mopnocarboxylic or dicarboxylic acid,the sum of the monomer compounds amounting to 100 parts by weight, characterized in that from 0.5 to 2.0 parts by weight of a chain transfer agent are used per 100 parts by weight of monomer. Said latices can be used for producing pressure-sensitive adhesives.
