Abstract:
A composition of matter comprising an admixture or reaction product of:A) at least one metallocene corresponding to the formula Cp.sub.l MX.sub.m X'.sub.n X"".sub.p, or a dimer thereof, wherein:Cp is an anionic, delocalized, .pi.-bonded group that is bound to M, containing up to 50 non-hydrogen atoms, optionally two Cp groups may be joined together forming a bridged structure, or further optionally one Cp is bound to X;M is a metal of Group 4 of the Periodic Table of the Elements in the +2, +3 or +4 formal oxidation state;X is an optional, divalent substituent of up to 50 non-hydrogen atoms that together with Cp forms a metallocycle with M;X' at each occurrence is an optional neutral Lewis base having up to 20 non-hydrogen atoms;X"" each occurrence is a monovalent, anionic moiety having up to 40 non-hydrogen atoms, optionally, two X"" groups are covalently bound together forming a divalent dianionic moiety having both valences bound to M, or, optionally 2 X"" groups are covalently bound together to form a neutral, conjugated or nonconjugated diene, or further optionally one or more X"" and one or more X' groups are bonded together thereby forming a moiety that is both covalently bound to M and coordinated thereto by means of a Lewis base functional group;l is 0, 1 or 2;m is 0 or 1;n is a number from 0 to 3;p is an integer from 0 to 3; andthe sum, l+m+p, is equal to the formal oxidation state of M, except when 2 X"" groups together form a neutral conjugated or non-conjugated diene, in which case the sum l+m is equal to the formal oxidation state of M; andB) at least one boratabenzene compound of Formula 1 or 2: ##STR13##wherein:R' is a fluoro-substituted hydrocarbyl group;each R"" is independently H, or an unsubstituted or inertly substituted hydrocarbyl, silylhydrocarbyl, perfluorohydrocarbyl, alkoxide or dihydrocarbyl amido group, and the hydrocarbyl group is a linear, branched, cyclic, aromatic, alkyl aromatic, or arylalkyl group,and two or more R"" groups, or R' including at least one R"" group are optionally joined into a ring or rings which are aromatic, cycloalkyl, or heteroatom rings or combinations thereof;and further optionally each R' and R"" independently is or comprises a linking group having at least one functional group capable of reaction with a support, with an inorganic oxide matrix of a support, with residual hydroxyl functional groups of a support, or with reactive silane functional groups on a support; andG.sup.+ is a cation selected from the group consisting of, [NHR.sub.3 ].sup.+, [NR.sub.4 ].sup.+, [SiR.sub.3 ].sup.+, [CPh.sub.3 ].sup.+, [(C.sub.5 H.sub.5).sub.2 Fe].sup.+ and Ag.sup.+, where R is independently in each occurrence a hydrocarbyl, silylhydrocarbyl, or perfluorocarbyl group of from 1 to 24 carbons.
