As results, the contents of three original pimaric-type resin acids, namely pimaric, isopimaric and sandaracopimaric acids, generally decreased, the higher the initial content with the higher the temperature and longer time, the faster the content declined.

结果表明，脂松香中原有的3种海松酸型树脂酸即海松酸、异海松酸、山达海松酸的含量总体呈下降趋势，初始含量越高、热处理温度越高、时间越长，其含量下降幅度越大。

Water-based resin approximately150, such as Rosin monomaleate monomaleate, styryl, acrylic copolymer resins, such as aminosulfonic ethylacrylate, emulsio, that is, there is a water-based dispersion resins, vinyl acetate copolymer, acrylic copolymer, polyurethane resin, epoxy resin, etc.

水性树脂的种类很多，如松香马来酸树脂、苯乙烯马来酸树脂、丙烯酸共聚物、氨基丙烯酸乙酯等，高分子乳液，即水性分散树脂，有醋酸乙烯共聚物、丙烯酸共聚物、聚氨酯树脂、环氧树脂等。
