Abstract

Abstract Translated from German Bei der Polymerisation von Propylen und anderen höheren 1-Olefinen erhält man in Gegenwart eines Katalysatorsystems aus einer Zirkonverbindung, welche stereorigid und chiral ist, und einen linearen oder cyclischen Aluminoxan Polymerisate, die einen hohen lsotaktizitätsgrad aufweisen und eine enge Molekulargewichtsverteilung besitzen. Das Katalysatorsystem ist außerdem außerordentlich aktiv. The polymerization of propylene and other higher 1-olefins gives, in the presence of a catalyst system, a zirconium compound which is stereorigid and chiral and a linear or cyclic aluminoxane polymer which has a high degree of isotacticity and a narrow molecular weight distribution. The catalyst system is also extremely active.
