Hydrocarbon soluble polymetalated 1-alkene compositions are described, and these compositions may be characterized by the formula (I) wherein R is hydrogen, a hydrocarbyl group or R1M, M is an alkali metal, R1 is adivalent 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 R1 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 1alkyne, an organometallic compound R.degree.M, and a 1,3-conjugated diene wherein R.degree. is B hydrocarbyl group, M is an alkali metal, the mole ratio of conjugated diene to 1alkyne is at least about 2:1, and the reaction is conducted at a temperatuare of at least about 70.degree.C.
