固态缩聚尼龙66的熔化行为

摘要/Abstract

摘要： 关于固态缩聚反应的研究国内外已有报道.但未见固态缩聚尼龙66(SSPPA66)熔化行为的报道.本文用DSC方法研究了固态缩聚尼龙66的熔化行为,分析其产生熔融双峰的原因.

Abstract: By using DSC techniques,the melting behvior of nascent polyamide-66 preparedby solid state polycondensation (SSPPA66) and SSPPA66 film casted from formic acid solution has been investigated. A single melting peak for nascent SSPPA66 and double meltingpeaks for SSPPA66 film were observed.It appeared that in the SSPPA66 film there are twokinds of crystal with different crystalline structure.

Key words: nylon66, solid state polycondensate, melting behvior, differential:canning calo-rimetry
