Abstract
A polymer contains a succinimide ring substituted on the nitrogen atom by a reactive group, where the ring is supported either by the main chain or by a side chain, resulting from reacting at least one polyolefin with at least one compound containing a maleimide ring substituted on the nitrogen atom by a reactive group with formula --R--(X).sub.n where X is a reactive group, n is a whole positive number equal to 1 or more and R is a residue containing at least one carbon atom, and with at least one polyepoxide containing at least two epoxy groups in its molecule. These polymers can be used for the production of co-extruded products, multi-layered materials, surface coatings and polymer alloys.
