Synthesis of polyisobutylene star-branched polymers via living carbocationic polymerization |
| 摘要 |
The present invention is the synthesis of star polymers containing polyisobutylene (PIB) via the arm-first, core-last method. These polymers are superior in properties to known hydrogenated polyisoprene star-branched polymers due to their inherent lack of unsaturation.
