摘　　要：采用凝胶渗透色谱(GPC)法测定辛基酚醛增粘树脂相对分子质量及其分布,并研究辛基酚醛增粘树脂相对分子质量对其软化点和增粘效果的影响。确定的测试条件为:流速1.0 mL·min^(-1),柱温40℃,试样溶液质量浓度(2±0.2) mg·mL^(-1);辛基酚醛增粘树脂的软化点和增粘效果随着其相对分子质量的增大而提高。The relative molecular weight and distribution of octyl phenolic tackifying resin were determined by the gel permeation chromatography(GPC),and the effects of octyl phenolic tackifying resin on its softening point and tackifying effect were studied.The determined test conditions were as follows:flow rate 1.0 mL·min^(-1),column temperature 40℃,sample solution mass concentration(2±0.2)mL·min^(-1).The softening point and tackifying effect of octyl phenolic resin increased with the increase of its relative molecular weight.
