ACTIVE HYDROGEN-CONTAINING COMPOSITIONS CONTAINING A SECONDARY AMINETERMINATED ADDUCT OF A PRIMARY AMINE COMPOUND & A POLYEPOXIDE AND POLYUREA-CONTAINING POLYMERS PREPARED

摘要

Polymers having high impact strength, high modulus and high heat distortion temperatures are prepared by reacting a polyisocyanate with a secondary amine terminated adduct of a polyepoxide and a primary amine.
