Abstract:
A process of forming a polymerization catalyst represented by the formulae: whereineach R and Râ€³ independently represents a C4-C24 hydrocarbyl selected from the group consisting of an alkyl, a cycloalkyl, an aryl, an aralkyl, a substituted aryl having at least one position of the aromatic group substituted with a C1-C12 alkyl or a fused or unfused aryl group and a hydrocarbyl terminated oxyhydrocarbylene group; G represents an oxygen or sulfur atom; E represents an OH, SH, or NHR group; J represents â€”Oâ€”, â€”Nâ€” or â€”Sâ€” as part of a ring structure; RVI represents hydrogen, aryl, Si(OR)3, or a tri(C1-C12 hydrocarbyl)methyl group wherein each R is independently a C1-C12 hydrocarbyl; âˆª represents a hydrocarbylene group selected from the group consisting of arylene, arylalkylene, alkarylene, cycloalkylene, alkylene group, and mixtures thereof and wherein said group has carbon-carbon single covalent bonds only or combined with non-aromatic or aromatic carbon-carbon ethylenic double bonds within the hydrocarbylene group; M represents a metal selected from the group consisting of Fe, Co, Ni, Ru, Rh, Pd, Os, Ir, and Pt; and Sol represents a polar solvent molecule: comprising contacting a ligand compound free of electron-withdrawing groups which is selected from a compound represented by the general formulae: â€ƒwherein R, G, E, J and âˆª are as defined above; and each Râ€² and Râ€³ independently is selected from hydrogen or an R group, as stated above, provided at least one Râ€² and Râ€³ is a hydrogen: with a di(tertiary amine) late transition metal reagent represented by the formula: â€ƒwherein Râ€²â€³ represents hydrogen or a C1-C5 alkyl or substituted alkyl; each RIV and RV independently represents a hydrocarbyl, or each RIV together and each RV together represents a hydrocarbylene group; RIV is as defined above; M is the above defined transition metal in the +2 oxidation state; and n represents an integer of from 0 to 3.
