摘要
对松香与顺丁烯二酸酐的Ｄｉｅｌｓ－Ａｌｄｅｒ反应进行了研究，讨论了反应温度、反应时间和反应物摩尔比对反应的影响；并进一步制得端羟基马来松香；对含端羟基马来松香酯的硬质聚氨酯泡沫塑料的耐热性进行了研究。
The Diels-Alder reaction of rosin and maleic anhydride was investigated,effectof temperature,reaction time and ratio of reactants on reaction was discussed,then the hydroxyl-terminated maleic rosin ester was prepared. The heat resistance of rigidpolyurethane foamed plastics modified by hydroxyl-terminated maleic rosin ester Was studied.
