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. The polyalloocimenes of this invention have a majority of the residual unsaturation present in pendent dimethylbutadienyl groups. The polyalloocimenes of this invention are useful in of themselves as film forming binders for inks, as tackifiers for hot melt adhesive and the like. The polyalloocimenes of this invention are also especially useful as intermediates. The presence of the substantial amount of unsaturation and particularly the conjugated unsaturation of the pendent groups make the polyalloocimenes of this invention exceptionally reactive. For example Diels-Alder adducts of the polyalloocimene of this invention and an activated olefin can readily be prepared. The adducts which are formed are useful as binder resins in printer ink, coating and adhesive formulations.
