【Abstract】 The effect of diethylene glycol content on the properties of unsaturated p - olyester resin and on the mechanical properties(tensile, flexural, impact, comp- ress and hardness) of their casting and fiberglass-resinforced plastics were well investigated. The role of isomcrization catalysts (KBr) played on the activity of resins were also studied. Hence, the optimal content of diethylene glycol and KBr in the unsaturated polyester resin were found.更多还原
