COPOLYMERS PREPARED BY USING BOTH ANIONIC POLYMERIZATION TECHNIQUES AND COORDINATION CATALYSTS |
摘要 |
A process for forming a copolymer comprising the steps of (i) preparing a living polymer segment by using anionic polymerization techniques, (ii) modifying the living polymer by reacting it with an alkyl metal halide to form an organometallic polymeric intermediate, and (iii) preparing a second polymer segment from the organometallic polymeric intermediate by combining the intermediate, conjugated diene monomer, and a coordination catalyst that will polymerize the conjugated diene monomer.
