Abstract

PURPOSE: To prepare a vinyl chloride polymer having excellent thermal stability and flowability in the kneading process, and excellent transparency and gelation properties, by (co)polymerizing vinyl chloride in the presence of a specific amount of a benzyl alcohol derivative and an alkyl vinyl ether.
CONSTITUTION: A vinyl chloride polymer having an average polymerization degree of 600W800 is prepared by suspension polymerization of (A) 100 parts by weight of monomers comprising vinyl chloride alone or its mixture with copolymerizable monomers (e.g. vinyl acetate, etc.), in the presence of (B) 0.01W5.0 parts by weight of a benzyl alcohol expressed by the formula (R is 1W4C alkyl; n is 0W2) and (C) 0W5.0 parts by weight of an alkyl vinyl ether (alkyl group is 4W18C linear or branched).
EFFECT: The component (B) has chain transfer effect and also increases the thermal stability. Addition of the component (C) further increases the effects.
