Abstract:
A catalyst comprising:(A) a transition metal compound having the formula: (C.sub.5 R.sup.1.sub.5)MQ.sub.3, wherein each R.sup.1 substituent is independently selected from the group consisting of hydrogen, a C.sub.1 -C.sub.8 alkyl, an aryl, and a heteroatom-substituted aryl or alkyl; wherein two or more R.sup.1 substituents may be linked together forming a ring; M is a transition metal of Group IVB of the Periodic Table of the Elements; and each Q substituent is independently selected from the group consisting of a C.sub.1 -C.sub.20 carboxylate and a C.sub.1 -C.sub.20 carbamate;(B) a non-phenolic compound having the formula R.sup.5 H, wherein R.sup.5 is a tertiary alkoxy having 4 to 25 carbons, a siloxy moiety (R.sup.6).sub.3 SiO--, wherein each R.sup.6 is the same or different and is a linear or branched alkyl having 1 to 8 carbon atoms, or a thiolato moiety of 4 to 25 carbons; and(C) an aluminoxane.
