摘要

The sequence distribution and the terminal structures of poly-1

3-pentadiene chains obtained by rare earth catalyst and effect of polymerization temperature on microstructure of the polymer have been investigated by 13C-NMR method. According to experimental results it was supposed that terminal active growing chain of the polymer would be four types of anti- and syn-η3-allyl structures. When polymerization temperature was reduced

the content of cis-1

4-poly-1

3-pcntadiene increases. It can be explained by isomerization between anti-and syn-η3-allyl.The process forming trans-1

2 unit instead of 3

4-unit were also described.
