N2 - Pd complexes with diimine ligands promote cyclopolymerization of diallylmalonates to afford a polymer having cyclopentane group. Herein we report the copolymerization of I with ethylene and a-olefins promoted by the Pd complexes. The copolymerization proceeds smoothly to give the polymer having trans- 1,2-disubstituted cyclopentane repeating unit. Content of I unit in the copolymer varies from 3 to 42% depending on the reaction conditions. The polyethylene with high content of I is linear, while decrease of I content renders the polymer branched. The copolymerization of I with propylene also proceeded to afford the copolymer with increased content of I. The copolymer of I with ethylene or propylene is rich in random sequence, and that with 1-hexene or 1-decene is of block structure. Other dienes such as diethyl diallylmalonate and N.N-diallyl sulfonamides also undergo copolymerization with ethylene and α-olefin in the presence of palladium catalysts to afford the copolymer having trans-l,2-disubstituted cyclopentane repeating unit.
