Abstract: An improved polymer and a process for the preparation of impact resistant styrene graft copolymers. Ethylene-propylenetercomponent-rubber is dissolved in styrene, then acrylonitrile is added to a styrene to acrylo-nitrile ratio of 6/1 to 4/1, the polymerization is carried out in the mass until the end of the phase transition, further acrylonitrile, and optionally further styrene, is added and the polymerization is completed in the mass or in suspension.

Abstract: of the disclosure: Polyolefins having a broad molecular weight distribution are obtained in a very high yield even using, as the catalyst, a product from the reaction of a magnesium alcoholate with titanium tetrachloride, if the reaction between the magnesium alcoholate and the titanium tetrachloride is carried out at a relatively low temperature and the reaction mixture is then heated to a fairly high temperature in order to split of alkyl chlorides.

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: PROCESS FOR PREPARING IMPACT RESISTANT POLYVINYL AROMATICS of the disclosure The invention relates to novel impact resistant graft copolymers of a vinyl aromatic on an EPTR especially characterized by an improved notched impact strengnth and resistancy 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.
