    摘要: The invention refers to a linear, isotactic polymer which has a structure of one or several C2 to C20 olefins, of which the isotacticity, due to a statistic distribution of stereoscopic errors in the polymer chain, is within the range of from 25 to 60% of [mmmm] pentad concentration with the proviso that an arbitrary or rather regular sequence of isotactic and atactic blocks is excluded, the polymer having a mean molecular weight Mw within the range of from 100,000 to 800,000 gms/mol and a TG of from −50 to +30.

    摘要: A catalyst system suitable for the polymerization of C.sub.2 -C.sub.10 -alk-1-enes comprising, as active ingredients, a complex compound of metals in Sub-groups IV and V of the Periodic Table and an oligomeric alumoxan compound is obtained by a procedure in which metals in Sub-groups IV and V of the Periodic Table are mixed with the oligomeric alumoxan compound and the resulting mixture is then applied to finely divided polymer. The catalyst system of the invention can be isolated after manufacture and is particularly suitable for the gas-phase polymerization of C.sub.2 -C.sub.10 -alk-1-enes.
