High performance resin reaction products of carboxyl terminated 1, 2- polybutadiene with epoxides and acid terminated difunctional aliphatic alcohols

摘要

A functionally terminated polybutadiene polymer is reacted with an epoxide to produce an epoxide terminated polybutadiene. A toughening agent and a peroxide free radical initiator are mixed with the epoxy terminated polybutadiene, and upon reaction a tough thermoset resin is produced having advanced chemical, electrical, and thermomechanical properties. Particular improvements are in the resistant-to-moisture and the tensile strain-to-failure properties.
