Abstract:
A polymerization or oligomerization reaction comprising polymerizing or oligomerizing ethylenically unsaturated monomers in the presence of a composition comprising(1) a compound characterized by the general formula â€ƒwherein each R1 and R2 is independently selected from the group consisting of hydrogen, halogens, alkyl, substituted alkyl, cycloalkyl, substituted cycloalkyl, heteroalkyl, heterocycloalkyl, substituted heterocycloalkyl, aryl, substituted aryl, heteroaryl, substituted heteroaryl, alkoxy, aryloxy, silyl, boryl, phosphino, amino, thio, seleno, and combinations thereof, optionally, R1 and R2 are joined together in a ring structure; R3 is independently selected from the group consisting of alkyl), substituted alkyl, cycloalkyl, substituted cycloalkyl, heterocycloalkyl, substituted heterocycloalkyl, aryl, substituted aryl, heteroaryl, substituted heteroaryl, and silyl; Q1 and Q2are, independently, selected from the group consisting of hydrogen, alkyl, substituted alkyl, cycloalkyl, substituted cycloalkyl, heterocycloalkyl, substituted heterocycloalkyl, aryl, substituted aryl, heteroaryl, substituted heteroaryl, alkoxy, aryloxy, silyl, boryl, phosphino, amino, thio seleno, and combinations thereof, optionally, Q1 and Q2 are joined together in a ring structure; X is selected from the group consisting of oxygen or sulfur; (2) a metal precursor characterized by the general formula M(L)n, where M is a transition metal selected from the group consisting of Sc, Y, and Groups 4, 5, 6, 7, 8, 9, 10, 11, and 12 of the Periodic Table of the Elements; L is independently each occurrence a ligand; n is 0, 1, 2, 3,4, or 5; and, (3) optionally, at least one activator.
