摘要
制备了聚酰胺6/聚乙烯醇(PA6/PVA)共混物,通过DMA、FTIR、DSC和力学性能测试等方法对共混物进行了表征,利用Hoffman-Weeks方程和Flory熔点下降方程求得了PA6的平衡熔点和两种聚合物的相互作用参数,研究了共混物的相容性和力学性能。结果表明:在氢键的作用下,PA6/PVA共混物具有良好的相容性;PA6与PVA相互作用参数为-0.085,进一步证明了PA6/PVA共混物是热力学相容体系;当PVA含量为50%时,PA6/PVA共混物的相容性和力学性能最佳。
PA6/PVA blend was characterized by DMA, FTIR, DSC and mechanical property test. The equilibrium melting point of PA6 and interaction parameter of two polymers were worked out by Hoffman-Weeks equation and Flory melting point depression equation. The compatibility and mechanical property of the blend were studied. The results show that： the compatibility of PA61 PVA blend is excellent because of the function of hydrogen bond; the interaction parameter between PA6 and PVA is -0.085, which further proves PA61PVA blend is thermal dynamic compatible system; when PVA content is 50%, the compatibility and mechanical property of PA6/ PVA blend are the best.
