PROCESS OF COUPLING ALKALI METAL-TERMINATED POLYMERS WITH SILICIC COMPOUND IN PRESENCE OF CONJUGATED DIENES |
摘要 |
The coupling of alkali metal-terminated polymers with silicic coupling agents is significantly improved, both as to the rate of coupling and the efficiency of coupling, by the inclusion of a conjugated diene in a coupling procedure with the silicic coupling compound.
