Using nitric oxide to reduce reactor fouling during polypropylene graft copolymerization |
| abstract |
A graft copolymer comprising a backbone of a propylene polymer material havingna 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 bynfree radicals, and (3) removing any unreacted grafting monomer from the graftncopolymerized propylene polymer material, decomposing any unreacted initiator, andndeactivating any residual free radicals in the material, wherein (1) and (2) are carried outnin the presence of a continuous feed of nitric oxide. The nitric oxide reduces the build-upnof polymer deposits on reactor walls and gas circulation loops while having almostnno effect on the graft copolymerization reaction. |
