Abstract: The invention relates to novel impact resistant graft copolymers of a vinyl aromatic on an ethylene/propylene/tercomponent rubber especially characterized by an improved notched impact strength and resistance to atmospheric corrosion, and a process for their preparation. Said copolymers are obtained by a two-step mass/suspension polymerization process characterized by the presence of oxygen, preferably by the presence of air, at a pressure of from 0.05 to 10 atmospheres gauge during the course of the mass polymerization step.

Abstract: There are idsclosed novel flame-proofing agents for plastics, especially for homopolymers and copolymers of sytrene and acrylonitrile. These agents are organic compounds containing bromine and one or two phosphinic acid groups. Besides the good flame-retarding properties these compounds have the advantage that they do not adversely affect the shrinking of foamed plastics.

Abstract: The present invention relates to expandable polystyrene beads showing a high resistance to heat at temperatures of up to about 50.degree.C. Said improved beads are obtained by incorporating into them 0.01 to 0.5% by weight of octafluorocyclobutane in addition to the usual hydrocarbon blowing agent.
