A process for the preparation of new copolymers of olefins or olefins and non-conjugated dienes with unsaturated furan and/or thiophene derivatives, by co-ordination catalysis is disclosed. The copolymers of present invention are characterized by the fact that the monomers derived from furan or thiophene have the formula Where X represents oxygen or sulphur, p equals 0 or 1, and R.sub.1 represents, when p equals 0, a vinyl radical or m being an integer from 0 to 12, and, when p equals 1, an alkenyl radical of from 2 to 20 carbon atoms. These copolymers can replace polyolefins or copolymers of olefins or olefins and dienes, in cases where resistance to ultra-violet radiation is needed.
A substantially linear high-molecular weight copolymer consisting of non-polar groups derived from at least one alpha-olefin selected from the group consisting of ethylene, propene and 1-butene, and mixtures of ethylene and propene and polar groups derived from at least one member selected from the group consisting of vinyl furan, vinyl thiophene and a compound of the formula ##SPC7##
A vulcanized composition containing a substantially linear high-molecular weight copolymer consisting of non-polar groups derived from at least one alpha-olefin selected from the group consisting of ethylene, propene and 1-butene, and mixtures of ethylene and propene and polar groups derived from at least one member selected from the group consisting of vinyl furan, vinyl thiophene and and a compound of the formula ##SPC10##
