IN SITU BLOCK COPOLYMER FORMATION DURING POLYMERIZATION OF A VINYL AROMATIC MONOMER |
| 摘要 |
The present invention is a free radical bulk polymerization process for producing a rubber modified polymer from a vinyl aromatic monomer comprising: polymerizing the vinyl aromatic monomer in the presence of a diene rubber having at least one stable free radical group, under polymerization conditions such that a vinyl aromatic-diene block and/or graft copolymer rubber is formed.
