carbosilane segments and of rigid phenylene moieties (1 and 2) were synthesized and investigated in order to evaluate their heat-curing behavior (epoxy homopolymerization) as well as thermal and mechanical properties of the networked polymers. Differential scanning calorimetry (DSC) analysis revealed that melting points of both diepoxides were −73.9 and −50.7 °C, respectively. Networked polymers of 1 and
合成并研究了两种由挠性碳硅烷片段和刚性亚苯基部分(1和2)组成的二缩水甘油醚,以评估它们的热固化行为(环氧均聚)以及网络聚合物的热和机械性能。差示扫描量热法(DSC)分析显示,两种二环氧化物的熔点分别为-73.9和-50.7°C。1和2的网状聚合物的玻璃化转变温度(T g)分别低于环境温度2.2和18.7°C。固化的1和2具有很高的热稳定性通过热重分析(TGA)确认(5%失重温度(T d5)= 369°C为1和351°C为2)。固化的1和2的拉伸试验表明,它们的杨氏模量分别为(9.76±0.135)-2和(1.29±0.114)-1 MPa。
