摘要
以β-蒎烯／马来酸酐共聚物为主链，接枝聚乙二醇单甲醚，合成一种梳状高分子表面活性剂，并对产物进行了表征。讨论了反应物相对分子质量、反应物配比及反应时间对表面张力的影响，采用相反转乳化技术将其应用于松香酯乳液。结果表明，产物具有良好的表面活性，采用相对分子质量为6300的β-蒎烯／马来酸酐共聚物为主链，接枝聚乙二醇单甲醚-500，2种反应物按照酸酐与羟基的摩尔比为1：1进行反应，反应时间为12～16h时，反应产物降低水溶液表面张力的效果最好，产物制备松香酯乳液效果良好。
A comb-like surfactant is prepared by grafting monomethyl ether polyethylene glycol toβ-piene/maleic anhydride copolymer, then characterized. Its surface active properties are studied with various molecular weights, ratios of the reactants, and reaction time investigated. It can be used in rosin ester emulsions by phase inversion emulsion technique. Results show that the product has good surface activity, with molecular weight of 6 600 ofβ-piene/maleic anhydride copolymer grafting monomethyl ether polyethylene glycol-500, with mole ratio of two reactants of 1 ： 1 and under the room temperature to react for 12 to 16 hours, the best effect of the product to reduce the surface tension of the aqueous solution can be achieved, and it has a good result in making rosin ester emulsions.
