TERPOLYMERS

Novel high temperature thermoset terpolymers may be synthesized by reacting an alpha-substituted olefin, an alpha,beta-disubstituted olefin and a dual function monomer followed by cross-linking the resultant polymer with a low molecular weight multifunctional amine as the cross-linking agent in the presence of a catalyst. The resulting cross-linking agent is then cured at an elevated temperature to provide the desired terpolymer. This compound will possess desirable properties such as a low dielectric constant which renders it applicable for use as circuit board laminates.
