Abstract
PURPOSE: To prepare a non-toxic polyvinyl chloride having improved gelation characteristics, thermal stability and processability, by polymerizing vinyl chloride, etc. in the presence of a compound having a mercapto group and a hydroxyl group, a vinyl ether and a benzyl alcohol.
CONSTITUTION: (A) 100 parts by weight of vinyl chloride or its mixture with monomers copolymerizable therewith is polymerized in the presence of (B) 0.001W 0.1 parts by weight of a 2W6C compound having a mercapto group and a hydroxyl group, as a chain transfer agent, (C) 0.01W1.0 parts by weight of a 4W18C alkyl vinyl ether and (D) 0.01W1.0 parts by weight of a benzyl alcohol expressed by the formula (R is 1W4C alkyl; n is 0W2), to give the desired polymer.
EFFECT: The relatively low molecular weight and the improved processability due to the effect of the chain transfer agent.
