改性二聚酸聚酰胺树脂的性能及结构分析

Modifying and structure characterization of dimeric dibasic acid polyamide resin

用本体聚合的方法,通过化学改性,使低分子二聚酸聚酰胺树脂的性能得到大幅度提高。使用红外、差热、扫描电镜等大型分析仪器,对改性前后产品的结构进行表征,从结构上论证了产品性能提高的内在原因。将改性产品与国外进口同类产品进行类比,结果表明：性能完全达到同类进口产品水平。

The properties of lo w molecule dimeric dibasic acid polyamide resin were improved by chemical modified in mass polymerization.The structure of polymers were characterized by infrared spectrum, thermography and stereoscan. The reasons that the properties of product was highly increased was proved. Comparing with the import, The conclusion was that the properties of products can reach the oversea＇s level.
