Abstract:
A process for the polymerization of olefins, comprising, contacting under polymerizing conditions:(a) a first active polymerization catalyst for said olefins which contains a transition metal complex of a ligand selected from the groups consisting of: ##STR9## Ar.sup.1 Q.sub.p (VIII); R.sup.31 R.sup.32 N--CR.sup.33 R.sup.34 (CR.sup.35 R.sup.36).sub.m --NR.sup.31 R.sup.32 (IX) ##STR10## R.sup.47 R.sup.48 R.sup.49 P (XXII); ##STR11## and R.sup.31 S--CR.sup.33 R.sup.34 (CR.sup.35 R.sup.36).sub.m --SR.sup.31 (XXXVII)wherein:for (IV), (V), (VI) and (VII), the transition metal is selected from the group consisting of Fe, Co, Ni and Pd;for (VIII), (IX), (X), (XI), (XII), (XIII), (XIV), (XV), (XVI), (XVII), (XVIII), (XIX), (XX), (XXI), (XXII), (XXIII) and (XXXVII), the transition metal is selected from the group consisting of Ti, Zr, Sc, V, Cr, a rare earth metal, Fe, Co, Ni and Pd;Ar.sup.1 is an aromatic moiety with n free valencies, or diphenylmethyl;each Q is --NR.sup.52 R.sup.53 or --CR.sup.54 .dbd.NR.sup.55 ;p is 1 or 2;E is 2-thienyl or 2-furyl;each R.sup.52 is independently hydrogen, benzyl, substituted benzyl, phenyl or substituted phenyl;each R.sup.54 is independently hydrogen or hydrocarbyl; andeach R.sup.55 is independently a monovalent aromatic moiety;m is 1, 2 or 3;R.sup.53 is hydrogen or alkyl;each R.sup.33, R.sup.34, R.sup.35, and R.sup.36 is independently hydrogen, hydrocarbyl or substituted hydrocarbyl;each R.sup.31 is independently hydrocarbyl or substituted hydrocarbyl containing 2 or more carbon atoms;each R.sup.32 is independently hydrogen, hydrocarbyl or substituted hydrocarbyl;Ar.sup.2 is an aryl moiety;R.sup.38, R.sup.39, and R.sup.40 are each independently hydrogen, hydrocarbyl, substituted hydrocarbyl or an inert functional group;R.sup.37 and R.sup.41 are each independently hydrocarbyl, substituted hydrocarbyl or an inert functional group whose E.sub.s is about -0.4 or less;each R.sup.42 and R.sup.43 is independently hydrogen or acyl containing 1 to 20 carbon atoms;Ar.sup.3 is an aryl moiety;R.sup.45 and R.sup.46 are each independently hydrogen or hydrocarbyl;Ar.sup.4 is an aryl moiety;Ar.sup.5 and Ar.sup.6 are each independently hydrocarbyl;Ar.sup.7 and Ar.sup.8 are each independently an aryl moiety;Ar.sup.9 and Ar.sup.10 are each independently an aryl moiety or --CO.sub.2 R.sup.56, wherein R.sup.56 is alkyl containing 1 to 20 carbon atoms;Ar.sup.11 is an aryl moiety;R.sup.50 is hydrogen or hydrocarbyl;R.sup.51 is hydrocarbyl or --C(O)--NR.sup.50 --Ar.sup.11 ;R.sup.44 is aryl;R.sup.47 and R.sup.48 are each independently phenyl groups substituted by one or more alkoxy groups, each alkoxy group containing 1 to 20 carbon atoms;R.sup.49 is alkyl containing 1 to 20 carbon atoms, or an aryl moiety;R.sup.13 and R.sup.16 are each independently hydrocarbyl or substituted hydrocarbyl, provided that the carbon atom bound to the imino nitrogen atom has at least two carbon atoms bound to it;R.sup.14 and R.sup.15 are each independently hydrogen, hydrocarbyl, substituted hydrocarbyl, or R.sup.14 and R.sup.15 taken together are hydrocarbylene substituted hydrocarbylene to form a carbocyclic ring;R.sup.18 is hydrocarbyl or substituted hydrocarbyl, and R.sup.20 is hydrogen, hydrocarbyl or substituted hydrocarbyl or R.sup.18 and R.sup.20 taken together form a ring;R.sup.19 is hydrocarbyl or substituted hydrocarbyl, and R.sup.21 is hydrogen, substituted hydrocarbyl or hydrocarbyl, or R.sup.19 and R.sup.21 taken together form a ring;each R.sup.17 is independently hydrogen, substituted hydrocarbyl or hydrocarbyl, or two of R.sup.17 taken together form a ring;R.sup.27 and R.sup.30 are independently hydrocarbyl or substituted hydrocarbyl;R.sup.28 and R.sup.29 are each in independently hydrogen, hydrocarbyl or substituted hydrocarbyl; andn is 2 or 3;(b) a second active polymerization catalyst for said olefins which contains one or more transition metals;(c) at least one first olefin capable of being polymerized by said first active polymerization catalyst; and(d) at least one second olefin capable of being polymerized by said second active polymerization catalyst.
