CATALYST FOR HIGH TEMPERATURE OLEFIN POLYMERIZATION |
摘要 |
An olefin polymerization catalyst is prepared by (a) in a diluent, combining a diorganomagnesium compound with less than 2 molar equivalents of a first source of chloride to produce a "chloride deficient" magnesium chloride support; (b) without isolating any solids, adding a second source of chloride which reduces the amount of soluble un-reacted diorganomagnesium compound present; (c) without isolating any solids present, adding a tetravalent titanium species and; (d) adding an activator. The catalyst is active for solution polymerization of olefins. |
