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, the polymer 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)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. These polymers can be used for the production of co-extruded products, multi-layered materials, surface coatings and polymer alloys.
