摘　　要：丙烯海松酸 (1)与环氧氯丙烷在弱碱及相转移催化剂存在下反应得到丙烯海松酸二缩水甘油酯 (2 ) ,探索出较佳的反应路线 ,产物分离纯化后对其结构和性能进行了研究。并以此反应为基础 ,从丙烯酸改性松香出发 ,制备了主要成分为 2的丙烯酸改性松香环氧树脂 (3)。研究了 3分别与胺、聚酰胺及酸酐类固化剂的固化反应和固化产物的性能。结果表明 ,此种环氧树脂的固化过程及产物性能与E - 4 4环氧树脂相当。Bis-oxiranylmethyl ester of acrylic adduct of levopimaric acid (2) was prepared by acrylic adduct of levopimaric acid (1) with epichlorohydrin in the presence of phase-transfer catalyst.The structure and properties of 2 were studied.Following the same procedure,a new epoxy resin (3) based on 2 was synthesized by (reaction) of acrylic modified rosin with epichlorohydrin.Curing reactions of epoxy resin 3 with amine,polyamide and anhydride and (properties) of the cured products were investigated.Results of the experiments showed that epoxy resin 3 has the (corresponding) properties as E- 44 epoxy resin.
