Substituted cyclopentenes, such as alkyl cyclopentenes, are polymerized by selected .alpha.-imine complexes of nickel and palladium. The polymers are useful as molding resins or elastomers. Also disclosed herein are novel catalysts for the polymerization of cyclopentenes to form novel higher melting homopolycyclopentenes.

Замененные cyclopentenes, such as алкиловые cyclopentenes, полимеризованы выбранными комплексами alpha.-imina никеля и палладиума. Полимеры полезны как смолаы или эластомеры прессформы. Также показаны здесь катализаторы романа для полимерности cyclopentenes для того чтобы сформировать homopolycyclopentenes романа более высокие плавя.
