摘要
以4,4′-二羟基二苯砜为原料合成了二[4-(4-氨基苯氧基)苯基]砜(BAPS),采用红外光谱(FTIR)、元素分析(EA)和核磁共振氢谱(1H-NMR)等对其结构进行了表征;并以BAPS为扩链剂制备了含砜基聚氨酯弹性体,采用原子力显微镜(AFM)、FTIR、热失重(TG)、广角X-射线衍射(WAXD)和力学性能测试等手段研究了此弹性体的微相分离结构和性能。结果表明,所得产物BAPS的结构与预期设计相符;以BAPS为扩链剂合成的含砜基聚氨酯弹性体微相分离明显,具有较好的耐热性和机械性能。
The bis [ 4- （4-aminophenoxy） -phenyl ] sulfone （ BAPS ） was synthesized by 4,4′-dihydroxy diphenyl sulfone and characterized by means of FTIR, EA and 1 H-NMR. The obtained BAPS was used as a chain extender for preparing polyurethane elastomers. The microphase separation structure and properties were measured through F-FIR, WAXD, AFM, TG and tensile measurements. The results showed that the prepared BAPS structure was coincided with the designed one. The prepared polyurethane elastomers which contained sulfuryl group had a higher degree of microphase separation, better heat-resistance and high mechanical properties compared with the elastomers chain-extended MOCA.
