Abstract
1365501 Amorphous ethylene-alpha olefin copolymers IMPERIAL CHEMICAL INDUSTRIES Ltd 14 Feb 1972 [26 Feb 1971] 5548/71 Addition to 1314828 Heading C3P An amorphous, vulcanizable, elastomeric copolymer of ethylene, a C 3 -C 10 alpha olefin, and optionally a non-conjugated diene is prepared by contacting the monomers with a catalyst composition prepared by reacting a complex of formula R m MX p with an inert solid which has hydroxyl groups on its surface but is free from adsorbed water, the polymerization being carried out in an organic diluent in which the monomers and the greater part of the polymer product are soluble under the conditions of the reaction, where R is a hydrocarbon or substituted hydrocarbon group, M is a metal of Groups IVAVIA, X is a univalent anion or monodentate neutral ligand, m has a value from 2 to the maximum valency of M and n has a value from 0, to 2 less than the actual valency of M in the complex. The required amorphous polymer is the diluent-soluble portion of the product. It may be necessary to add one or more of the monomers continuously or in portions as the reaction proceeds to maintain a constant monomer ratio. Examples are given of the copolymerization of ethylene, propylene and, in some cases, ethylidene norbornene or 1,6-octadiene in decalin, heptane, toluene, ethylbenzene, 2,2, 4,6,6 - pentanethylheptane or chlorobenzene, catalysed by the product of reacting tetrabenzyl zirconium, tetrabenzyl titanium, tetrakis-(neopentyl) zirconium or (Me 3 SiCH 2 ) 4 Zr with y-alumina. Vulcanization of some of the pro. ducts is described.
