A process for preparation of diene styrene alpha-methylstyrene block polymers and polymers therefrom. |
| 摘要 |
<p>Diene-styrene- alpha -methylstyrene block polymers are prepared by polymerization in excess alpha -methylstyrene with a lithium initiator wherein styrene- alpha -methylstyrene block is polymerized at a temperature from 20 DEG to 160 DEG C with the ratio of styrene to alpha -methylstyrene being from 50:1 to 1:50.</p> |
