摘　　要：应用红外光谱技术对调合润滑油常用的传统聚异丁烯丁二酰亚胺类无灰分散剂进行分析,确定了单挂、双挂和高分子量聚异丁烯丁二酰亚胺无灰分散剂的红外光谱特征;并对国内和国外几种新型杂元素化(硼化、磷化)聚异丁烯丁二酰亚胺产品进行了红外特征对比分析,指出了国内外产品质量差异的根本原因。The traditional type of ashless dispersant used in lubricating oil was analyzed by infrared spectroscopy technique(IR).The results showed that the different structure type polyisobutylene succimides have different characteristic absorption.Furthermore,the root cause of quality difference was pointed out through comparing the infrared characteristic absorption of several kinds of boronized/phosphorated polyisobutylene succimide products at home and abroad.
