ABSTRACT:
Normally crystalline vinylidene halide polymers are prepared by an improved limited coalescence suspension polymerization reaction wherein colloidal silica is used as a solid particle emulsifier, and a low molecular weight, non-ionic, water-soluble cellulose ether, having a viscosity grade less than about 35 centipoise, is used as the stabilizing agent. Spheroidal polymer particles are obtained having a generally uniform, small size and superior flow properties.
