| abstract | 1382336 Ethylene-diene copolymers DU PONT OF CANADA Ltd 11 April 1972 [16 April 1971] 16617/72 Heading C3P Partially crystalline polymers of ethylene and 0À2 to 3À0 weight per cent of a α,#-diene of at least 8 carbon atoms or a cyclic endomethylenic diene, having less than 0À10 ethylenic double bonds per 100 carbon atoms and having an activation energy of viscous flow of at least 10, may be prepared by copolymerizing the monomers at 88‹ to 110‹ C. in the presence of a coordination catalyst. The catalyst may comprise an alkyl aluminium dichloride or sesquichloride and vanadium oxytrichloride or dialkoxide chloride, optionally with a promoter such as an N-alkyl trichloracetamide, alkyl 4,4<SP>1</SP>,4<SP>11</SP>-trichlorocrotonate or alkyl trichloracetate; and the polymerization may be effected in an inert hydrocarbon solvent, optionally in the presence of other olefins and/or hydrogen. In examples ethylene is continuously polymerized with (2 and 3) dinorbornene, (4) norbornadiene, (5) 1,7-octadiene, (6) dinorbornene and octene, (7) dinorbornene and 5-methylnorbornene and (9 and 10) norbornadiene and norbornene. |
