摘要
通过薄膜渗析、红外光谱、凝胶渗透色谱、皂化反应等一系列手段建立了一套对无灰分散剂的系统分析方法，并利用该方法得到了一种新型无灰分散剂及其衍生物的平均结构、相对分子质量分布、分散度等重要结构信息，得出该新型无灰分散剂的结构与传统无灰分散剂的结构不同。
A method for analysis of new type ashless dispersant was developed based on film permeation, IR analysis and saponification reaction, etc. Some important informations of the ashless dispersant and its derivants such as average molecular structure, molecular weight distribution and dispersity were obtained. The structure of the new type ashless dispersant was different from the conventional ones.
