Claims
- 1. A polymer containing at least one succinimide ring substituted on the nitrogen atom by a reactive group, said ring being supported either by the main chain or by a side chain, said polymer being a reaction product resulting from reacting a polyolefin being a high density polyethylene selected from the group consisting of a homopolymer of ethylene, a copolymer of ethylene constituted by at least 90% by weight of ethylene moieties and at most 10% by weight of a C3 to C8 olefin, and a polymer of a norbornene, 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 carboxylic group, n is a number equal to 1 or more and R is a residue containing at least one carbon atom.
- 2. A polymer consisting essentially of at least one succinimide ring substituted on the nitrogen atom by a reactive group, said ring being supported either by the main chain or by a side chain, said polymer being a reaction product resulting from reacting a polyolefin being a high density polyethylene selected from the group consisting of a homopolymer of ethylene, a copolymer of ethylene constituted by at least 90% by weight of ethylene moieties and at most 10% by weight of a C3 to C8 olefin, and a polymer of a norbornene, 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 selected from a carboxylic group, n is a number equal to 1 or more and R is a residue containing at least one carbon atom.
- 3. A polymer consisting of at least one succinimide ring substituted on the nitrogen atom by a reactive group, said ring being supported either by the main chain or by a side chain, said polymer being a reaction product resulting from reacting a polyolefin being a high density polyethylene selected from the group consisting of a homopolymer of ethylene, a copolymer of ethylene constituted by at least 90% by weight of ethylene moieties and at most 10% by weight of a C3 to C8 olefin, and a polymer of a norbornene, 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 selected from a carboxylic group, n is a number equal to 1 or more and R is a residue containing at least one carbon atom.
- 4. A polymer according to claim 1, in which group —R— is selected from a saturated or an unsaturated, a substituted or an unsubstituted aliphatic hydrocarbon, or a substituted or an unsubstituted aromatic group.
- 5. A polymer according to claim 1, in which the polyolefin is a copolymer of ethylene constituted by at least 90% by weight of ethylene moieties and at most 10% of a C3 to C8 olefin.
- 6. A polymer according to claim 1 in which the group —R— is a benezene residue and the group —X is in the position para to the nitrogen atom.
- 7. A process for the preparation of a polymer according to claim 1 comprising contacting a molten polyolefin in a mixer or extruder with at least one compound containing a maleimide ring substituted on a nitrogen atom by a reactive group.
- 8. A surface coating comprising a polymer according to claim 1.
- 9. A polymer alloy comprising a polymer according to claim 1.
- 10. A co-extruded product comprising a polymer according to claim 1.
- 11. A multi-layered product comprising a polymer according to claim 1.
- 12. A polymer prepared in accordance with the process of claim 1.
