Novel method for production of epoxy terminated butadiene and butadiene acrylonitrile copolymer tougheners synthesized through the use of hydroxyl terminated polybutadiene and hydroxyl terminated butadiene acrylonitrile copolymers as starting materials. The epoxy terminated butadiene and butadiene acrylonitrile copolymers synthesized by the novel method have unexpectedly lower viscosity, contain no free epoxy and provide good improvements in T-peel resistance over traditional tougheners produced using traditional methods. Adhesives, composites and coatings utilizing the tougheners of the inventive method are within the scope of the invention.
