Abstract

1412629 Polyolefin compositions KUREHA KAGAKU KOGYO KK 5 Oct 1972 [5 Oct 1971] 46000/72 Heading C3P Shaped compositions comprise (1) a polyolefin and (2) 50 to 90 weight per cent of an inorganic component at least the major constituent of which is calcium sulphite in the form of crystals having a smaller dimension of 1 to 30 microns and a larger dimension of 5 to 100 microns. The polyolefin may be a polymer of ethylene or propylene, or copolymer thereof with ethylene, propylene, butene, pentene, vinyl fluoride, fluorochloroethylene, vinyl acetate or an alkyl acrylate or methacrylate. The inorganic component may contain a minor proportion of gypsum, calcium carbonate, iron oxide, zinc oxide, silica sand, kieselguhr or talc. The products may be made soft and pliable by subjecting to mechanical stresses, e.g. by stretching and bending, to give leather-like porous products. Examples describe the preparation and stressing of sheets and plates of (1 and 3) polyethylene and calcium sulphite, and (2) polypropylene, calcium sulphite and calcium carbonate.
