Abstract

Polyvinyl chloride for use in plastisols is made by polymerizing the monomer in aqueous emulsion to a desired final conversion of monomer to polymer equivalent to 50 to 95 per cent of complete conversion, at a temperature from 40 DEG to 60 DEG C. to form a latex having an average particle diameter from 0.35 to 0.9 micron, and at any time between 50 and 95 per cent of the final conversion adding to the reaction mixture 0.1 to 10 per cent, based on the weight of unpolymerized vinyl chloride, of a molecular weight regulator, in such an amount that the intrinsic viscosity of the final polymer is not less than 0.75 measured in cyclohexanone at 30 DEG C., and after the desired final conversion of vinyl chloride to polymer, removing any unreacted residual vinyl chloride monomer and recovering the polyvinyl chloride from the latex. The polymerization may be effected in the presence of a small amount of a previously prepared polyvinyl chloride "seed" latex, and the emulsifying agent may be added portionwise. The polymerization is carried out in the presence of a catalyst, e.g. hydrogen peroxide or potassium persulphate. Specified emulsifiers are sodium laurate and the diamyl ester of sodium sulphosuccinic acid. Molecular weight regulators mentioned are bromoform, carbon tetrachloride, trichloroethane, bromodichloromethane, dibromochloromethane, ethylene dibromide, 1-bromo-1,1-dichloroethane, 1,2-dibromo - 1,1 - dichloroethane, trichloroethylene, tetrachloroethylene, isobutyraldehyde, ethyl dibromoacetate, ethyl bromomalonate, benzene sulphonyl chloride, p-tolyl sulphonyl chloride, p-bromo sulphonyl chloride, 1,1,1-tribromo-2-methyl propanol-2, allyl bromide, N-chlorophthalimide alkyl iodides, and phenacyl bromide. Specifications 627,265, 630,611 and 634,647 are referred to.
