1337075 Alkenylnorbornadiene terpolymers SNAM PROGETTI SpA 19 April 1971 [22 Jan 1970] 20418/71 Heading C3P A copolymer is obtainable from at least two mono-olefins and, as at least one triene, a 2- alkenyl-norbomadiene-2,5 of the formula where R is H or alkyl and RSP2-8/SP are each H or alkyl or aryl. The usual Zeigler catalysts and polymerization techniques may be employed. Polyiminoalanes may be used as the reducing aluminium compound component. In examples, 2 - (1SP1/SP - propenyl) - norbornadiene - 2,5 or 2- (2SP1/SP - but - 21 - enyl) - 3 - methyl - norbornadiene- 2,5-is copolymerized with ethylene and propylene in the presence of Al(C 2 H 5 ) 2 Cl and V(AcAc) 3 -AcAc is acetylacetonate-and purified using n-butanol (short-stopper), surfaceactive agent, stirring, acetic acid (emulsion breaker), H 2 O-acetic acid-EDTA (ethylenediaminetetraacetic acid), stirring, washing and acetone (precipitant).
