Versuchsvorschrift

A butadiene-styrene copolymer rubber latex having a particle size of 0.10 micron, a gel content of 75%, a swelling degree in toluene of 27 and a pH of 8.8 and comprising 70% of butadiene and 30% styrene was prepared. To 100 parts of the rubber latex 4.0 parts of a C.A. latex comprising 60% of n-butyl acrylate, 20% of methyl methacrylate and 20% of methacrylic acid and having a pH of 6.2 was added and, thereby, the particle size of the rubber latex was agglomerated to 0.75 micron. The pH of the agglomerated rubber latex was 7.9. The agglomerated rubber latex was then stabilized by the addition of 3.5% based on the dry rubber of polyoxyethylene lauryl ether. Four hundred parts of styrene was graft polymerized onto 100 parts (dry) of the agglomerated and stabilized rubber latex. The graft copolymer thus obtained had an Izod Impact Strength of 17.6 kg-cm/cm2.
