Optimization of Synthetic Parameters of High-purity Trifunctional Mercaptoesters and Their Curing Behavior for Thiol-epoxy Click Reaction |
| 초록 |
The direct esterification reaction between 3-mercaptopropionic acid (3-MPA) and trimethylolpropane (TMP) was conducted in the presence of various catalyst concentrations of p-toluenesulfonic acid (p-TSA) to examine the optimized synthetic condition to produce the high-purity trimethylolpropane-tris(3-mercaptopropionate) (TMPMP). The purity of desired TMPMP and uncompleted side-product reduced as the acid catalyst concentration in this esterification reaction increased while the generation of thioester-based side-product increased. The equivalent ratio between epoxy and the manufactured TMPMP was maintained at 1:1 to monitor the curing behavior of thiol-epoxy click reaction by DSC technique. Thermal features of base-catalyzed TMPMP-cured epoxy resin were assessed according to the purity of the TMPMP curing agent. |
