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 is disclosed an improved bulk-suspension process for polymerizing vinyl aromatic monomers in the presence of an ethylene-propylene-nonconjugated diene-rubber, which comprises using, in the suspension polymerization step, peroxy-carbonic esters as the polymerization initiator. The process of the invention yields products having improved notched impact strength, weatherability and elongation at break combined with a good shear stability.

Abstract: Polyolefins having a broad molecular weight distribution are obtained in a very high yield even using a catalyst based on a reaction product of a magnesium alcoholate with titanium tetrachloride, if the hydrocarbon-insoluble product of the reaction of the magnesium alcoholate with titanium tetrachloride is heated to a fairly high temperature with a chloroalkoxytitanate, in order to split off alkyl chlorides.
