Title:
黄変を抑えたカルボジイミド組成物、耐加水分解安定剤及び熱可塑性樹脂組成物
Document Type and Number:
Japanese Patent JP4585749
Kind Code:
B2
Abstract:
A carbodiimide composition having an improved heat resistance which had been a conventional requirement for a carbodiimide compound to be compounded in an ester-group-containing resin or a biodegradable plastic, exhibiting no coloring problems due to yellowing, and having more superior stabilizing effect against hydrolysis, a stabilizer against hydrolysis mainly comprising the carbodiimide composition and a thermoplastic resin composition containing the same. More specifically, a carbodiimide composition comprising a carbodiimide compound (A) and an antioxidant (B), having not lower than 250 DEG C of 5 % weight loss temperature as determined by a thermogravimetric (TG) method, wherein an antioxidant (B) is dispersed and present in the composition by admixing during synthesis of a carbodiimide compound (A), a stabilizer against hydrolysis mainly comprising the carbodiimide composition and a thermoplastic resin composition containing the same.
