| abstract | 1384939 Coated products CESKOSLOVENSKA AKADEMIE VED 2 Nov 1972 [5 Nov 1971] 50635/72 Heading B2E [Also in Division C3] A composition for forming leather substitutes comprises a plastisol of a vinyl chloride polymer a synthetic, hydrophilic, water-insoluble, cross-linked macromolecular filler containing polar groups capable of binding water reversibly and at least 10% by weight of the filler of a liquid which swells the filler and boils in the range 60-140‹C. Porous, hydrophilic sheets are obtained by applying the composition to a backing and heating, in two stages if necessary to evaporate the liquid, thereby forming a porous structure, and gel the polymer. In examples the polymer is PVC or a vinyl chloride-vinyl acetate copolymer, the filler is polymethacrylic acid, poly (2-hydroxethyl methacrylate), sodium polymethacrylate, polyacrylamide, or a polymer of the methacrylic ester of 2, 3-dihydroxypropyl trimethyl ammonium chloride. The liquid used is water or aqueous ethanol. Also added are plasticisers, stabilisers, lubricants, pigments and in one example a further blowing agent, azobisformamide. |
