ABSTRACT:
A monomer containing a strained olefin ring such as cyclobutene or cyclopropene is polymerized by forming a complex of the monomer and Cp.sub.2 TiCH.sub.2 -(Cp is .eta..sup.5 -C.sub.5 H.sub.5) and heating the complex in the presence of excess monomer to above the decomposition point. A controlled, selective opening of the ring with the strained olefin forms a linear, soluble polymer.
