摘要：The present disclosure is directed to a catalyst comprising the reaction productof:
(a) a silicon-containing compound having the structural formula R.sub.4--n SiX.sub.n --where R is C.sub.1 - C.sub.10 hydrocarbyl; X is halogen; and n is an integer of 1 to 4;< P>
(b) a magnesiumdialkyl having the structural formula R.sup. 1 R.sup.2 Mg, whereR.sup.1 and R.sup.2 are the same or different and are C.sub.2 -C.sub.10 alkyl;
(c) an alcohol having the structural formula R.sup.3 OH, where R.sup.3 is C.sub.1 -C.sub.10 hydrocarbyl;
(d) a halide-containing metal compound, said metal selected from the groupconsisting of titanium, zirconium and vanadium;
(e) an aluminum alkoxide having the structural formual Al(OR.sup.5).sub.3, whereR.sup.5 is C.sub.2 -C.sub.4 alkyl; and
(f) a halide-containing metal compound said metal selected from the group consistingof titanium, zirconium and vanadium, with the proviso that said reaction product is formedfrom said components (a) to (f) reacted in the order recited but for the interchangeability
of components (a) and (b).
The catalyst of this disclosure is useful, when provided in a catalytically effectiveamount and in the presence of co-catalytically effective amount of an organoaluminumcompound, in the polymerization of alpha-olefins.
