PREPARATION OF ETHYLENE TERPOLYMERS |
摘要 |
<p>Preparation of Ethylene Terpolymers Ethylene terpolymers with a low number average molecular weight of from 1500 to 5500 and a vinyl acetate content of from 10 to 20% by weight, useful in wax modifiers or petroleum fraction additives, are prepared by high pressure polymerization (at least 500 bar and 150.degree.C) in presence of 10 to 25% by weight of an iso olefin such as isobutylene. Incorporation of the iso olefin gives terpolymer products containing from 3 to 13% weight of iso olefin.</p> |
