Process for the polymerization of vinyl chloride in an aqueous phase |
摘要 |
A process for the polymerization of vinyl chloride in an aqueous phase in the presence of oil-soluble free-radical initiators and a mixture of at least two high-molecular, surface-active suspending agents is described. This mixture is composed of 10 to 90% by weight (relative to the mixture) of at least one copolymer formed from vinyl acetate and a compound of the formula R1-CO-NR2-CH=CH2 wherein R1 is H or alkyl having 1 to 4 C atoms and R2 is H or methyl, and of 90 to 10% by weight (relative to the mixture) of at least one cellulose ether or a partially acetylated polyvinyl alcohol. Homopolymers, copolymers or graft copolymers of vinyl chloride which have an improved combination of properties are obtained.
