Procedure

By use of the Dienoxy A copolymer described above, a 1,2-polybutadiene epoxy copolymer composition of approximately 33/67 composition was prepared and both the epoxy constituent and the polybutadiene constituent were cured. It should be noted that the blend of Dienoxy A copolymer with the additional diglycidylether of bisphenol A (DGEBA) and the anhydride curative system formed a stable dispersion while a blend of 1,2-polybutadiene with DGEBA and the anhydride curative system rapidly separated into two phases.
