Morphology control in polypropylene graft copolymers |
| abstract |
A graft copolymer comprising a backbone of a propylene polymer materialnhaving a vinyl monomer graft polymerized thereto is produced by (1) treating a propylenenpolymer material with a free radical polymerization initiator, (2) treating the propylenenpolymer material with at least one grafting monomer capable of being polymerized by freenradicals, in the presence of a polymerization rate modifier, and (3) removing any unreactedngrafting monomer from the graft copolymerized propylene polymer material, decomposingnany unreacted initiator, and deactivating any residual free radicals in the material. Use ofnthe polymerization rate modifier increases the polymerization induction time on thenpolymer surface, consequently facilitating monomer diffusion into the interior of thenpolymer particles so that surface polymerization of the monomer is inhibited. |
