Abstract

PURPOSE: To prepare a polyvinyl chloride almost free from discoloration and having improved thermal stability, in high productivity, by using a specific peroxide safe to deal with, active at lower temperatures and excellent in durability of activity in polymerization, as a polymerization initiator.
CONSTITUTION: 100pts.wt. vinyl chloride monomer or its mixture with monomers copolymerizable therewith (e.g. styrene, vinyl acetate, etc.) is suspension-polymerized preferably at 40W60°C in the presence of preferably 0.005W0.5pt.wt. a compound expressed by the formula (R1 is ≥3C alkyl; R2 is ≥1C alkyl) as a catalyst.
