| titleOfInvention | MORPHOLOGY CONTROL IN POLYPROPYLENE INJERTO COPOLYMERS |
| abstract | A graft copolymer comprising a skeleton of a propylene material having a polymerized vinyl monomer graft therein is produced: (1) treating a propylene polymer material with a free radical polymerization initiator, (2) treating the Propylene polymer material with at least one graft monomer capable of being polymerized by free radicals, in the presence of a polymerization rate modifier and (3) removing any graft monomer that has not reacted from the copolymerized propylene polymer material, decomposing any initiator that has not reacted and deactivating any residual free radical in the material. The use of the polymerization rate modifier increases the polymerization induction time on the polymer surface, thereby facilitating the diffusion of the monomer inside the polymer particles so that the surface polymerization of the monomer is inhibited. |
