Abstract

A procedure was suggested for preparing epoxy ether urethane oligomers via intermediate oligodiisocyanates with increased content of the starting 2,4-toluene diisocyanate. The procedure allows preparation of epoxy-containing oligomers with appreciable fraction of low-molecular-mass diglycidyl urethane. The presence of diglycidyl urethane in the binder enhances not only the adhesion but also the strength of the cured material without significantly affecting the glass transition point of the binder. Elastic materials prepared by curing the compounds studied with cylcoaliphatic amines exhibit enhanced levels of strength and low-temperature elasticity.
