ABSTRACT:
A method for preparing a polyolefine--vinyl polymer composite, wherein about 10-200 parts by weight of vinyl monomer and about 0.01-4.0 parts by weight of a free radical polymerization initiator, based on 100 parts by weight of vinyl monomer, are impregnated in 100 parts of weight of polyolefine particles by slowly mixing these at a temperature of about 20.degree.-130.degree. C. while maintaining the particle structure of the polyolefine. After 50-99% of the amount of the monomer has been absorbed into the polyolefine particles, a water suspension is prepared by adding to the above-mentioned mixture about 80-1000 parts by weight water, based on 100 parts of weight of polyolefine+vinyl monomer, as well as a stabilizing agent. The temperature of the water suspension is then increased for polymerizing the vinyl monomer.
