ABSTRACT:
Novel composite polymer particles are obtained, under specified conditions, by preparing an aqueous suspension comprising 100 parts by weight of propylene polymer particles, 5 - 200 parts of a vinyl or vinylidene monomer, and a specific polymerization initiator; heating the aqueous suspension to impregnate the propylene polymer particles with the monomer; and then raising the temperature of the aqueous suspension to complete polymerization of the monomer. The resultant composite polymer is improved in molding, mechanical, chemical and physical properties and is useful as molding or forming material as it is or as a blend with another polymeric material.
