摘要: 醇酸树脂的分级对于指导生产具有重要的意义。因为自凝胶色谱图得到的量太少,不能进行各个级分性质的考察。因此提出测定各个级分的酸值,将酸值和特性黏数、相对分子质量一样,作为一个特性参数用于醇酸树脂分级数据的处理。本法适用于长油度醇酸树脂。

Abstract: The fractionation of alkyd resin is of importance for directing production. Because the fractonal quantity was obtained from gel permeation chromatography was too small to investigate properties of various fraction .Therefore,this paper has introduced a new approach, in which the acid value is used as a characteristic parameter like intrinsic viscosity or molecular weight to treat with the data of fractionation of alkyd resin. This method is suited to long oil alkyd resin.

Key words: alkyd resin, fractionation, acid value
