摘要: 如同顺-1,4-聚丁二烯(PBd)和聚异戊二烯(PIP),在一定的催化条件下,顺-1,4-丁二烯-异戊二烯无规共聚物(PBI,简称丁戊无规共聚物)可生成环化顺-1,4-丁戊无规共聚物(CP-BI)。作者曾报道用裂解色谱法表征环化顺-1,4-聚丁二烯(CPBd),本文对不同组成的CPBI和PBI进行了裂解色谱比较研究。

Abstract: The cyclized random copolymers of cis-i, 4-butadiene and isoprene have been investigated by using pyrolysis-gas chromatography. The results show that the amount of main pyrolysis products changes regularly with the degree of cyclization. Both units of butadiene and isoprene participate in cyclization, but the butadiene units are less liable to be cyclized.

Key words: cis-1,4-polybutadiene, polyisoprene, pyrolysis-gas chromatography, cyclization
