PRGRAMMED ADDITION OF HEAVY ETHERS FOR MICROSTRUCTURE CONTROL DIENE POLYMERS. |
| 摘要 |
A process for the polymerization of dienes which comprises anionically polymerizing dienes in the presence of an anionic polymerization initiator and a microstructure control agent is improved by adding the control agent to the polymerization mixture in two or more doses to closely control the vinyl content of the polymer produce.
