摘　　要：利用己内酰胺(CL)单体,采用阴离子原位聚合方法制得了聚芳醚砜(PPES)/MC尼龙6复合材料。FTIR分析结果表明,PPES与己内酰胺之间存在一定的氢键相互作用,使得PPES在己内酰胺熔体中能够很好地溶解。SEM结果表明PPES在MC尼龙6基体中能够较好地分散。差示扫描量热法和X射线衍射法分析结果表明复合材料中PPES对MC尼龙6的结晶起异相成核作用,提高了MC尼龙6的结晶温度,但不改变MC尼龙6的α晶型结构。TG结果表明PPES的加入提高了复合材料的热稳定性能。With caprolactam （CL） as monomer, poly （ phthalazinon ether sulfone） （~PPES） /monomer casting （MC） nylon 6 composite was prepared by means of anionic in-situ polymerization, and the structure and property of the composite were characterized by means of FTIR, SEM, DSC, XRD and TG. The results of FTIR analysis demonstrated hydrogen bonds interactedbetween PPES and CL, which made PPES well solved in CL melt. SEM observation showed PPES well dispersed in MC nylon 6 matrix. DSC and XRD analysis demonstrated PPES played the role of heterogeneous nucleating agent and increased the crystallization temperature of MC nylon 6, while the crystal structure of MC nylon 6 was unchanged. The TG curves illustrated the addition of PPES improved theheat Stability of MC nylon 6.
