| titleOfInvention | Improvements in and relating to the production of vinyl chloride polymers |
| abstract | Vinyl chloride polymer dispersions are made by polymerizing vinyl chloride alone or admixed with another copolymerizable monomer, in aqueous media, in the presence of a dissolved polymerization catalyst, and an emulsifying agent which is introduced only after the polymerization has commenced but before any coagulation occurs, e.g. after a decrease in the vapour pressure of the system. The ingredients of the polymerizable mixture may be added stepwise or continuously. The polymer may be separated from the dispersion by coagulation or spray-drying. Specified emulsifying agents are sodium lauryl sulphate, sodium oleyl sulphate, sodium cetyl sulphate, the sodium salt of sulphonated castor oil, the sodium and ammonium salts of sulphonated or sulphated methyl oleate, sodium oleate, sodium palmitate, sodium stearate, ammonium palmitate, ammonium stearate and ammonium oleate. The copolymerizable monomer may be vinyl acetate, vinyl propionate, vinyl butyrate, vinylidene chloride, acrylonitrile, ethyl acrylate, methyl methacrylate, methyl alpha-chloroacrylate, maleic acid, fumaric acid, diethyl maleate, and diethyl fumarate. Catalysts mentioned are hydrogen peroxide and the alkali metal and ammonium persulphates. The catalysts may be used in conjunction with copper salts or with oxygen, as described in Specifications 589,264 and 598,777. The dispersions may be used for treating textiles, paper, felt and yarns, and may contain pigments, fillers and heat-stabilizers. The polymers may be used for the production of pastes in admixture with plasticizers, as described in Specification 589,715. Plasticizers mentioned are tricresyl phosphate, dibutyl sebacate, dibutyl phthalate, branched chain octyl and nonyl phthalates and linear polyesters such as those described in Specification 624,393. Specification 427,494 also is referred to. |
