Abstract
Novel compounds having the formula R.sub.n Al(OR.sub.f).sub.3-n in which R is a C.sub.1 -C.sub.6 alkyl group, R.sub.f is a C.sub.1- C.sub.6 fluoroalkyl group, and 0.ltoreq.n<3 have been found suitable as Ziegler-Natta type co-catalyst components for polymerization or co-polymerization of olefins.
