用C36二聚酸、癸二酸与1，4-丁二醇二缩水甘油醚和双酚A型环氧树脂进行扩链反应，制备柔韧性环氧树脂预聚体。考察了配方组成、反应温度和催化剂等因素对羧基转化率的影响。结果表明，对于所给配方，当催化剂用量为0.1%，140℃下反应2 h，反应基本完全。另外，以柔韧性环氧树脂预聚体为基体树脂制备的固化物拉伸强度达到12.0 MPa，断裂伸长率为85%。

We process extender chain reaction with C36 dimer acid, sebacic acid, 1,4-butanediol diglycidyl and bisphenol A type epoxy resin, and produce flexible epoxy resin prepolymers. We investigate the influence of carboxyl conversion rate from formula composition, reaction temperature and catalyst and other factors. The results show that, for given formula, when the dosage of catalyst is 0.1%,it reacts 2h under 140 ℃, and the re-action is substantially complete. In addition, the flexibility of a cured epoxy resin prepolymer matrix resin composition prepared by a tensile strength of 12.0 MPa, elongation at break of 85%.
