| titleOfInvention | Irradiation process for making olefin graft copolymers with low molecular weight side chains |
| abstract | Graft copolymers are prepared, in a non-oxidizing atmosphere, by (1) irradiating a particulate olefin polymer material with high energy ionizing radiation, (2) treating the irradiated olefin polymer material with at least one grafting monomer that is capable of forming side chains on the olefin polymer material, in the presence of at least one additive to control the molecular weight of the side chains of the polymerized grafting monomer selected from (a) at least one hydroxylamine derivative polymerization inhibitor, and (b) at least one thio-, or nitro-, or halogen-substituted aliphatic or aromatic compound or an aliphatic or aromatic phosphine derivative, and (3) deactivating the residual free radicals in the resulting grafted olefin polymer material and removing an unreacted vinyl monomer from the material. Graft copolymers with low molecular weight side chains are produced that are easier to process and have improved internal and surface morphology. |
