Substantially linear copolymers derived from at least one acyclic aliphatic olefin monomer and at least one nitrogen containing vinyl monomer, wherein the at least one nitrogen containing vinyl monomer is according to Formula (I) (see formula I) wherein R19 is selected from -C=C, and -C(O)-C=C; wherein R20 and R21 are independently selected from H, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, a biphenyl group, a carboxylate group, a carboxyalkyl group, a carboxyarylalkyl group, an alkoxy group, an alkenyloxy group, an alkynyloxy group, an aryloxy group, an alkoxycarbonyl group, and derivatives thereof. Also disclosed are methods of making such copolymers using late transition metal catalyst complexes.

Copolymères substantiellement linéaires obtenus à partir d'au moins un monomère oléfinique aliphatique acyclique et d'au moins un monomère vinylique azoté de formule (I) (voir la formule I) dans laquelle R19 est choisi entre -C=C- et -C(O)-C=C-, R20 et R21 sont choisis de manière indépendante parmi H, un groupe alkyle, un groupe alcényle, un groupe alcynyle, un groupe aryle, un groupe biphényle, un groupe carboxylate, un groupe carboxyalkyle, un groupe carboxyarylalkyle, un groupe alcoxy, un groupe alcényloxy, un groupe alcynyloxy, un groupe aryloxy, un groupe alcoxycarbonyle, et des dérivés de ceux-ci. Divulgation également de méthodes de production de tels copolymères en utilisant des complexes catalyseurs de métaux de transition.
