Procedure

ABS-2 a graft copolymer obtained by grafting 26.5 parts by weight of styrene and 8.3 parts by weight of acrylonitrile on 65.2 parts by weight of a polybutadiene latex. The content of non-grafted styrene-acrylonitrile copolymer (SAN) obtained in the grafting reaction of the isolated ABS was approximately 6.3% by weight. The weight ratio styrene to acrylonitrile in the SAN was approximately 2.7. The weight-averaged molecular weight of the SAN was approximately 78,000. The particle size of the butadiene rubber is indicated in the appended Figure and in the table hereinafter. The gel content was 95% by weight.
