ABSTRACT OF THE DISCLOSURE Substantially gel-free copolymers of cyclopentene with dicyclopentadiene are prepared by polymerizing these monomers in the presence or (1) a catalyst comprising (a) at least one compound selected from the group consisting of dialkylaluminum iodides, alkylaluminum diiodides and mix- tures of trialkylaluminum compounds with elemental iodine and (b) at least one solvent- or monomer-soluble tungsten compound, and (2) at least one nonconjugated acyclic carbon having at least one hydrogen on each double-bonded carbon atom. Catalyst component (a) is charged before catalyst component (b).
