工品の品質安定性に劣るという問題がある。Organic materials such as plastic and rubber are decomposed and deteriorated by supply of heat, light, oxygen and other external energy. Phosphorous esters have been used in various plastics, rubbers and the like as a decomposition / deterioration inhibitor for preventing such decomposition / deterioration. Phosphite esters are generally added during the polymerization reaction of plastics or during molding. However, among the phosphites, TNP is particularly viscous, and when it is used as an anti-decomposition agent, it is difficult to obtain a homogeneous plastic compound at the compounding stage at the time of molding. Further, there is a problem that the quality stability of the molded product is poor.
