Abstract
Hydrocarbon soluble polymetalated 1-alkene compositions are described, and these compositions may be characterized by the formula ##STR1## wherein R is hydrogen, a hydrocarbyl group or R.sup.1 M, M is an alkali metal, R.sup.1 is a divalent oligomeric hydrocarbyl group comprising moieties derived from a conjugated diene, and wherein the total number moieties derived from a conjugated diene in all of the R.sup.1 groups in Formula I is from about 2 to about 30. Preferably, the alkali metal is lithium. Hydrocarbon soluble polymetalated 1-alkene catalysts for anionic polymerizations are also described which comprise the reaction product of a 1-alkyne, an organometallic compount R.degree.M, and a 1,3-conjugated diene wherein R.degree. is a hydrocarbyl group, M is an alkali metal, the mole ratio of conjugated diene to 1-alkyne is at least about 2:1, and the reaction is conducted at a temperature of at least about 70.degree. C.
