Abstract

PURPOSE: To prepare dimethylaminoethyl trimellitate catalyst having a reduced volatile content and excellent latent curing accelerating ability, by reacting trimellitic anhydride with dimethylaminothanol in the absence of solvents.
CONSTITUTION: I Mole of trimellitic anhydride is reacted with 1.3W2 mole of dimethylaminoethanol in the absence of slvents until the acid anhydride groups are consumed completely. A catalyst for the curing of epoxy resins in prepared by drying the product under vacuum pressure of ≤ 20 mmHg to attain the voltatile content of ≤ 1.4 wt.%.
