裂解色谱法研究环化顺-1,4-丁二烯-异戊二烯无规共聚物
摘要:
如同顺-1,4-聚丁二烯(PBd)和聚异戊二烯(PIP)[1,2],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)[3],本文对不同组成的CPBI和PBI进行了裂解色谱比较研究。表1所列试样由实验室合成。用CDS pyro-probe 190型裂解器,SP-2305E型气相色谱仪,FID。裂解温度700℃,裂解时间5秒,色谱柱4mm×3m不锈钢柱,填充20% SE-30固定相(101白色担体),柱温106℃,载气氮气40mL/min。

PYROLYSIS-GAS CHROMATOGRAPHIC STUDY OF CYCLIZED RANDOM COPOLYMER OF CIS-1,4-BUTADIENE AND ISOPRENE
Abstract:
The cyclized random copolymers of cis-1,4-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.
