ABSTRACT:
An improvement in the method of preparing vinyl halide-containing polymers by suspension polymerization is disclosed. Briefly, the improvement comprises "tail-peaking" the reaction mass prior to stripping in order to remove vinyl halide. By "tail-peaking" is meant increasing the temperature of polymerization towards the latter part of the polymerization reaction. In one aspect the improvement comprises the additional feature of conducting the polymerization in the presence of a plasticizer.
