Anthranilates of polyoxyethylated carboxylic acid

摘要

Bis-anthranilates of the formula <IMAGE> (I) <IMAGE> +TR <IMAGE> or mixtures thereof, in which, in the formula, m and n are each 0 or a number from 1 to 5 and the sum of m and n must be at least 1, y is 0 or 1 and X is an alkylene radical having 1 to 8 C atoms, para- or meta-phenylene or para-cyclohexylene. The novel compounds are valuable chain extenders and crosslinking agents for the production of polyurethanes and polyurea resins and are also suitable as curing agents for epoxide resins.
