    摘要： Ethylene (35-60 mols) and a C 3-10 a-olefin (65-40 mols) are copolymerized at a temperature of 40 to 80°C with a catalyst of (a) an oxyvanadium compound, (b) an organoaluminium compound and (c) a halogenated hydrocarbon ester, e.g. a perchlorocrotonic acid ester, in a mol ratio of (b) to (a) of ≧ 2.5 and of (c) to (a) of ≧ 1.5, in a hydrocarbon solvent. The polymer has a molar ratio of ethylene: a-olefin of 88:12 - 98:2, a number average mol. wt. of 35,000 - 80,000 and a ratio of wt. number average mol wt. of 1.8:1 - 3.0:1 determined by GPC. It has good transparency and is moldable to a film which is heat-sealable at low temperature.
