ABSTRACT:
A dispersion polymerization process for the preparation of styrene butadiene polymers with an average particle diameter of from about 0.1 to about 200 microns, which comprises (1) formation of a homogenous reaction medium, containing styrene and butadiene monomers in the presence of a steric stabilizer and a chain propagating amount of an initiator; and (2) heating said homogeneous reaction medium under pressure permitting polymerization thereby resulting in the formation of insoluble styrene butadiene polymer particles.
