摘要
本文对西德 BASF 公司的复鞣剂 Relugan RE 进行了剖析,通过 IR、NMR、元素分析、热重分析和示差扫描量热技术(DSC)等方法,确定其为丙烯酸和丙烯腈以3:1的配比进行水溶液共聚的产品,为了改善体系均匀性和透明度,加入了一种特殊的助溶剂。
In this paper we used varied methods including IR,NMR,TGA,DSC, elementary analyses etc.to dissect the retanning agent relugan RE which is a product of West German's BASF company.It has been proved that this re- tanning agent was synthesized by aqueous solution copolymerization at the weight rate of 3:1(acrylic acid:acrylonitrile).Forthmore it's necessary to add a special assistant solvent into this system for improving the homogen- eity and transparency.
