Procedure

Diglycidyl terephthalate (145 parts, 1.0 epoxy equivalent) was dissolved in 1,2-dimethoxyethane (145 parts). Diethyl amine (73 parts, 1 mol.) was added at room temperature. The mixture was heated at 60° C. for 20 hours and part of the solvent (75 parts) was stripped off in vacuo. The product, a light-brown viscous solution, had a solids content of 4.45 meq./g theory: 4.59). 2-hydroxy-3-diethylaminiopropyl groups per molecule: 2; molecular weight: 436 (calculated).
