Abstract: A novel class of alloocimene polymers have been prepared which are comprised of a mixture of polymer chain units of 2,3-alloocimene and 6,7-alloocimene. The novel polyalloocimenes of this invention are prepared by polymerizing alloocimene in a reaction mixture which contains a catalyst system comprised of a metal such as sodium and an aliphatic or cycloaliphatic ether such as 1,2-dimethoxyethane.

Abstract: Vanadium compound/organometallic compound/inorganic oxide catalyst compositions useful for the polymerization of ethylene to polymers having a molecular weight distribution that can be controlled by selection of the appropriate member of a particular family of vanadium compounds are obtained by using, as the vanadium component, at least one vanadium compound prepared by reacting one molar proportion of VOCl.sub.3 and/or VOBr.sub.3 with about 0.5 to 1 molar proportion of a diol corresponding to the formula HO-R-OH, wherein R is a divalent hydrocarbon radical having a chain length of 2 to 16 carbon atoms. The molecular weight distributions of polymers formed in the presence of the catalyst compositions are narrowed as the chain length of R is increased. The preferred vanadium compounds are those prepared by reacting VOCl.sub.3 with a diol wherein R is a straight- or branched-chain alkylene group containing 2 to 6 carbon atoms.
