In this study, the effect of alkenyl side-chain of succinic anhydride (SA) on the thermo-mechanical behaviors of diglycidylether of bisphenol A (DGEBA) epoxy resins was studied. The number of carbons in the side-chain of SA was varied from 6 to 14 and N, N-dimethylbenzylamine was used as an accelerator. As a result, the reactivity of SA with epoxide groups was decreased with increasing the length of the alkenyl side-chain of SA. The coefficient of thermal expansion (CET) of the systems was increased as the length of the alkenyl side-chain of SA increased. The effect of amount anhydride, thermoplastics, and fillers on the CTE of epoxy resins was also discussed. |
