Method of producing polymer solutions of polymers or copolymers of vinyl chloride series |
摘要 |
A method of producing a polymer or copolymer solution of vinyl chloride series, wherein polymerization of 100 parts by weight of a monomer mixture of at least 50 weight percent of vinyl chloride and less than 50 weight percent of one or more monomers copolymerizable therewith is carried out in a solvent mixture consisting essentially of 30 to 55 weight percent water, remainder N,N-dimethyl formamide, in the presence of 0.5 to 5 parts by weight of a salt of a monomeric compound having a sulphonic acid group and using an initiator for radical polymerization.
