溶剂型80％高固体分聚丙烯酸酯多元醇树脂的分子量对涂膜物性的影响

摘要

This paper discusses the influence of the molecular Weight of solvent-borne 80% solid content polyacrylic polyols resin on the film performance. Experiments results show that the film performance is unaffected with the molecular weight： Mw=4 155, Mn=1 902.%探讨了树脂分子量对80％高固体分聚丙烯酸酯多元醇树脂涂膜性能的影响。试验结果表明，分子量控制在Mw=4155、Mn=1902时涂膜耐化学性不受影响。
