monomer. Subsequent treatment with tosylhydrazide afforded the corresponding hydrogenated derivative. The hydrogenated polymer was found to exhibit high melting and decomposition temperatures as well as a relatively high Young’s modulus when compared to other polyolefins [e.g., hydrogenated poly(norbornene) and poly(ethylene)]. The enhanced thermal and mechanical properties were found to originate
使用Grubbs第三代催化剂合成并聚合了二氢杜瓦瓶(bicyclo [2.2.0] hex-2-ene)。相应的开环易位聚合反应以受控的方式进行,这取决于所生产的聚合物的分子量与单体与催化剂的进料比之间的线性关系以及通过暴露于其他物质而延伸聚合物链的能力单体。随后用甲苯磺酰肼处理得到相应的氢化衍生物。与其他聚烯烃[例如,氢化聚(降冰片烯)和聚(乙烯)]相比,发现氢化的聚合物表现出高的熔融和分解温度以及相对高的杨氏模量。
