为配合酚醛树脂、十八烷基苯乙烯基醚聚合物新材料的生产、催化条件下煤直接液 化的研究，建立了各试样分子量表征的高效凝胶渗透色谱法（ＨＰＧＰＣ），高分辨地测定了分子 量分布、重均分子量Ｍｗ、数均分子量Ｍｎ。表征了不同产品的组成特性，有效地指导了工艺生 产和基础研究
In order to meet the demand of phenolic resin, new material of octadecyl styryl ether polymer and direct liquefaction of coal under catalysis conditions, high performance gel permeation chromatography (HPGPC) The molecular weight distribution, the weight average molecular weight Mw, and the number average molecular weight Mn were measured. Characterized the composition of different products, effectively guide the process of production and basic research
