描述了1，4-苯二硫醇或双（4-巯基苯基）硫醚与双（烷氧基丙二烯）如1，4-双（丙二烯氧基）二甲苯和双（丙二烯氧基）乙烷的自由基多加成。硫醇基团被选择性地加到丙二烯氧基的末端双键上，得到主链中含有活性碳-碳双键的聚合物。随着反应时间的延长，聚合物中碳-碳双键的几何结构由E异构化为Z异构化。此外，聚合物容易通过主链中的碳-碳双键与刘易斯酸反应进行交联
Radical polyadditions of 1,4-benzenedithiol or bis(4-mercaptophenyl) sulfide to bi(alkoxyallene) such as 1,4-bis(allenyloxy)xylene and bi(allenyloxy)ethane are described. Thiol groups were added to the terminal double bonds of allenyloxy groups selectively to afford polymers containing reactive carbon-xarbon double bonds in the main chain. The geometrical structure of carbon-xarbon double bonds in the polymer was isomerized from E to Z forms with reaction time. Furthermore, the polymers easily underwent cross-linking by the reaction of carbon-carbon double bonds in the backbone with Lewis acids
