Abstract

PURPOSE: To improve the thermal discoloration resistance, by adding ε-caprolactam at a specified ratio to a polyester resin molding material containing a normally liquid crosslinking agent.
CONSTITUTION: In a polyester resin molding material prepared by adding a curing agent, filler, lubricant, coloring agent and additive to a polyester resin, iodine value 80W110, containing 5W25wt% normally liquid crosslinking agent; 8W16wt% polyester resin and 0.2W1wt% ε-caprolactam are mixed. If necessary, 0W1pt.wt. per 100pts.wt. polyester, phosphite ester such as triphenyl phosphite or tristearyl phosphite is further added. If the amount of the phosphite ester exceeds 1pt.wt. the thermal discoloration resistance is adversely affected. If necessary, 0W1pt.wt., per 100pts.wt. polyester resin, silane coupling agent is further added. It is requrired that the crosslinking agent be liquid at normal temperature. If the agent is solid, the productivity is decreased markedly because the amount of the resin which can be added is small.
