摘要： A stabilizer against hydrolysis, which can solve conventional problems of a carbodiimide compound compounded in an ester-group-containing resin or a biodegradable plastic as a stabilizer against hydrolysis, such as poor heat resistance and a coloring problem due to yellowing, and can provide enhanced resistance against hydrolysis, and a thermoplastic resin composition of an ester-group-containing resin or a biodegradable plastic containing the same. Specifically, that the stabilizer against hydrolysis includes a carbodiimide composition comprising an aliphatic carbodiimide compound (A) and a phosphorus antioxidant (B), preferably the stabilizer contains a carbodiimide composition wherein a phosphorus antioxidant (B1) is dispersed and present in the carbodiimide composition by admixing the phosphorus antioxidant (B1) during synthesis of the aliphatic carbodiimide compound (A), and a thermoplastic resin composition having a superior stability against hydrolysis, characterized in that said stabilizer against hydrolysis is compounded in an easily hydrolysable resin (C).
摘要翻译：一种抗水解稳定剂，其可以解决复合在含酯基树脂中的碳二亚胺化合物或生物可降解塑料作为抗水解稳定剂的常规问题，例如耐热性差和由于黄化引起的着色问题，并且可以提供增强的耐水解性和含酯基树脂的热塑性树脂组合物或含有这些树脂的含生物降解性塑料的热塑性树脂组合物。具体地说，抗水解稳定剂包括含有脂族碳二亚胺化合物（A）和磷抗氧化剂（B）的碳二亚胺组合物，优选稳定剂含有碳抗氧化剂（B 1）在脂肪族碳二亚胺化合物（A）的合成过程中，通过混合磷抗氧化剂（B 1→1）和具有优异的抗水解稳定性的热塑性树脂组合物，分散并存在于碳二亚胺组合物中，其特征在于所述抗水解稳定剂在容易水解的树脂（C）中复合。
