A carbodiimide composition with suppressed yellowing, a process for its production, a stabilizer against hydrolysis and a thermoplastic resin composition

摘要

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.
