Process for the polymerisation and copolymerisation of vinyl chloride in suspension.

摘要

An improved process for the polymerisation and copolymerisation of vinyl chloride in suspension, characterised by using, together with the normal polymerisation agents, a single suspending agent consisting of partially saponified polyvinyl acetate of medium degree of hydrolysis, prepared by the controlled alkaline alcoholysis of polyvinyl acetate in the presence of methyl acetate.
