ABSTRACT:
Polyvinyl acetate polymers produced by mass polymerization or suspension polymerization are stabilized against blocking by addition of minor amounts of a silicon oxide compound during the pelletization process of mass polymerized polymers and prior to or during fluidized bed drying in the case of suspension polymerized polymers. The free flowing polymers are suitable for use as chewing gum bases, and for other uses.
