Block copolymers utilizing a mixture of cis and trans-isomers of 1,3-pentadiene |
摘要 |
Block copolymers having two or more blocks may be prepared from vinyl-substituted aromatic hydrocarbons and a mixed isomer mixture of 1,3-pentadiene. At least one block is polymerized from the cis and trans-isomer mixture of 1,3-pentadiene. The amount of the mixed isomer mixture of 1,3-pentadiene polymerized may be increased by including in the mixed isomer mixture a cis-isomer polymerization promoter.
