Abstract: THE PRESENT INVENTION RELATES TO CRYSTAL CLEAR GRAFT COPOLYMERS OF HIGH IMPACT STRENGHT AND THEIR MANUFACTURE BY POLYMERIZING VINYL CHLORIDE TO AN EXTENT OF POLYMERIZATION OF 50 TO 85%, THEN ADDING AN ELASTOMER LATEX OBTAINED FROM BUTADIENE, STYRENE AND VINYL ESTERS, IN AN AMOUNT WITHIN THE RANGE OF FROM 1 TO 30% BY WEIGHT CALCULATED ON THE VINYL CHORIDE AND FINALLY CONTINUING THE POLYMERIZATION OF THE WHOLE MIXTURE. THE RESULTING GRAFT COPOLYMERS CAN BE USED EITHER ALONE OR IN ADMIXTURE WITH SUSPENSION OR MASS POLYVINYL CHLORIDE FOR MAKING CRYSTAL CLEAR SHAPED ARTICLES OF HIGH NOTCHED IMPACT TENSILE STRENGTH.

Abstract: THE PRESENT INVENTION RELATES TO RIGID SHEETS ON THE BASIS OF POLYVINYL CHLORIDE, PLASTOMERS AND ELASTOMERS, SAID SHEETS BEING OBTAINED BY A CALENDERING PROCESS. THE MATERIAL COMPRISES (A) AN EMULSION HOMO- OR COPOLYMER OF VINYL CHLORIDE, (B) A SUSPENSION POLYMER OF VINYL CHLORIDE, (C) A GRAFT COPOLYMER OF VINYL CHLORIDE BASED ON A CROSS-LINKED COPOLYMER OF A CONJUGATED DIENE AND ACRYLOOR METHACRYLONITRILE, AND EVENTUALLY (D) A CROSS-LINKED ELASTOMERIC COPOLYMER SIMILAR TO THE BASIC COPOLYMER OF (C). THE SHEETS ACCORDING TO THE INVENTION HAVE AN IMPROVED IMPACT RESISTANCE AND DEEP-DRAWING PROPERTIES IN COMBINATION WITH A GOOD TRANSPARENCY AND GOOD OTHER PHYSICAL CONSTANTS.

Abstract: A polymer mixture comprises (a) 50 to 70% by weight of an emulsion homopolymer or copolymer of vinyl chloride having a K value of 58 to 72; (b) 10 to 30% of a suspension polymer of vinyl chloride having a K value of 50 to 65; and (c) 0.5 to 40% of a graft copolymer of vinyl chloride which has been prepared by the emulsion polymerization technique and in which the vinyl chloride is grafted on a cross-linked copolymer of a conjugated diene and acrylonitrile or methacrylonitrile having a gel content of more than 90%, the graft copolymer being insoluble in organic solvents; the percentages being calculated on the total weight of the mixture. The mixture may also contain (d) 1 to 10% of a cross-linked elastomeric copolymer prepared by emulsion polymerization of a conjugated diene and acrylonitrile or methacrylonitrile, said copolymer being insoluble in organic solvents and having a gel content of more than 80%. Other possible ingredients of the mixture are a stabilizer comprising (i) diphenyl thiourea or alpha-phenyl indole, epoxidized natural oils and an alkalizing water-soluble salt or (ii) an epoxy compound, an organo tin compound, a heavy metal salt of a fatty acid or a mixture of aminocrotonic acid esters of fatty alcohols; and a wax, fatty acid ester or polyolefin as lubricating agent. In the example, the mixture comprises (a) an emulsion polymerized vinyl chloride homopolymer, (b) a suspension polymerized vinyl chloride homopolymer, (c) a graft polymer of vinyl chloride on a cross-linked butadiene-acrylonitrile copolymer, (d) a butadiene-acrylonitrile elastomer, diphenyl thiourea, di-n-octyl tin-bis-thiogly-collic acid octyl ester, epoxidized soybean oil and montan wax.
