1‐Benzocyclobutenyl methacrylate‐bearing methacrylate (BCBMA) backbone has been synthesized, and radical polymerization of the monomer was performed by utilizing 2, 2′‐azobisisobutyronitrile (AIBN) as initiator to result poly‐BCBMA. Differential scanning calorimetry (DSC) measurement of the derived poly‐BCBMA revealed the lowering of thermal isomerization temperature from that of nonsubstituted benzocyclobutene. The thermal decomposition temperature of BCBMA before and after thermal treatment was confirmed by thermogravimetric analysis (TGA). The results of the TGA observation did not show significant difference in both 5% and 10% weight loss temperature (T_d5 and T_d10). This result suggests that the thermal conversion of the poly‐BCBMA to the networked polymer take place without thermal decomposition of the main chain based on the methacrylate framework. © 2019 Wiley Periodicals, Inc.

含聚甲基丙烯酸酯的苯并环丁烯结构的合成，并基于热异构化反应扩展为网络聚合物

合成了带有甲基丙烯酸1-苄基环丁烯基酯的甲基丙烯酸酯（BCBMA）主链，并利用2，2'-偶氮二异丁腈（AIBN）作为引发剂进行了单体的自由基聚合反应，从而得到了聚BCBMA。衍生的聚-BCBMA的差示扫描量热法（DSC）测量表明，热异构化温度比未取代的苯并环丁烯低。通过热重分析（TGA）确定了BCBMA在热处理之前和之后的热分解温度。TGA观察的结果在5％和10％的减肥温度下均未显示出显着差异（T _d5和T _d10）。该结果表明，聚-BCBMA向网络聚合物的热转化没有发生基于甲基丙烯酸酯骨架的主链的热分解。©2019 Wiley Periodicals，Inc.J.Polym。科学，A部分：Polym。化学 2019，57，2175–2180
