摘要:
1,1-DIALKYLETHYLENES, SUCH AS ISOBUTENE, PROMOTE THE PRIMARY LITHIUM INITIATED POLYMERIZATION OF MONOVINYL-AROMATIC COMPOUNDS, SUCH AS STYRENE, EITHER IN HOMOPOLYMERIZATIONS, OR IN THE FORMATION OF A-B-A block copolymers or (A-B).sub.a Z radial block copolymers, such as by sequential monomer addition with conjugated dienes.

1,1-DIALKYLETHYLENES, SUCH AS ISOBUTENE, PROMOTE THE PRIMARY LITHIUM INITIATED POLYMERIZATION OF MONOVINYL-AROMATIC COMPOUNDS, SUCH AS SYTRENE, EITHER IN HOMOPOLYMERIZATIONS, OR IN THE FORMATION OF A--B--A block copolymers or (A--B).sub.a Z radial block copolymers, such as by sequential monomer addition with conjugated dienes.
摘要:
Gel formation in the first reactor means of a multireactor process is suppressed by the employment of a silicon halide in the first reactor means in an organolithium-initiated, solution-polymerized, randomized, conjugated diene/monovinyl-substituted aromatic compound copolymerization.
