Abstract: PROBLEM TO BE SOLVED: To obtain a new carbodiimide composed of a specific carbodiimide and useful as a stabilizer for the hydrolytic decomposition of a plastic composed mainly of a polyester. SOLUTION: The objective carbodiimide is based on 1,3-bis(1-methyl-1- isocyanatoethyl)benzene and contains 12-40 wt.% of ethylene oxide unit [CH2 - CH2 - O] based on the carbodiimide and the structural unit of formula I, e.g. a compound of formula II [R is NHCONHR1 or NHCOOR1 (R1 is a group derived from an isocyanate-reactive compound); (n) is 0-10]. The carbodiimide can be produced by reacting 1,3-bis(1-methyl-1-isocyanatoethyl)benzene in the presence of a catalyst to eliminate carbon dioxide and form a carbodiimide and reacting the carbodiimide with a compound reactive with isocyanate and having the ethylene oxide unit.
