Abstract

1299400 Graft polymer compositions SHINETSU CHEMICAL CO 29 Dec 1970 [30 Dec 1969] 61660/70 Heading C3G A method of preparing vinyl chloride resin compositions comprises: (1) conducting polymerization in a polymerization vessel, containing an aqueous emulsion and having two inlets, by continuously pouring into the vessel 10-90 parts by weight of a diene rubber polymer, through one of the inlets, and 90-10 parts by weight complementarily of methyl methacrylate and 5-180 parts by weight of styrene through the other inlet, from 20 to 80% of the methyl methacrylate being added first, on its own, and the remainder of the methyl methacrylate being added subsequently mixed with the styrene, (2) recovering the graft polymer thus obtained from the aqueous emulsion, and (3) adding 30-1 parts by weight of the graft polymer with agitation to 70-99 parts by weight of vinyl chloride resin. The diene rubber polymer may be polybutadiene or a butadiene-styrene copolymer prepared by copolymerizing a mixture comprising styrene and at least 50% of butadiene. The polymerization may be carried out at 40-70‹ C. for 2-10 hours in the presence of a known polymerization catalyst, such as a redox catalyst of a peroxide such as cumene hydroperoxide or diisopropylbenzoyl peroxide and an iron salt such as ferrous sulphate. The amount of aqueous emulsion used in the first step is preferably such that the concentration. of the graft polymer product in the reaction liquid is 40-50% by weight and the aqueous emulsion may be prepared by adding 0À1-10 parts by weight of an emulsifier to 100 parts by weight of water. The emulsifier may be disproportionated rosin soap, tetrahydroabietic soap, dextropimaric soap or lauryl soap. The graft polymer is recovered by being salted out, filtered off and dried. The vinyl chloride resin may be vinyl chloride homopolymer and copolymers of vinyl chloride and a copolymerizable ethylenically unsaturated monomer, such as vinyl acetate, acrylonitrile, vinylidene chloride, vinyl ether or an α-olefin, and comprising at least 80% of vinyl chloride units. The vinyl chloride resin preferably has a polymerization degree of 600 to 1300. The amount of styrene added in admixture with the methyl methacrylate is 0À5-2 times the total amount of methyl methacrylate used. The vinyl chloride resin compositions may be used to prepare sheet material products which have the property of when being folded of not forming white creases.
