Production of a Polymer Binder Based on Benzocyclobutene for the Manufacture of Microwave-Range Materials

Abstract

A new copolymer based on benzocyclobutene-4-yl vinyldimethylsilane has been developed and synthesized for application in the manufacture of printed circuit boards. The influence of the copolymer composition on the viscosity of its solutions in mesitylene has been established, and concentration dependences of viscosity have been obtained. The possibility of using solutions of the benzocyclobutene-4-yl vinyldimethylsilane copolymer as a binder for producing prepregs for the manufacture of fiberglass laminates has been demonstrated. The dielectric properties of the obtained fiberglass laminate allow recommending it for use in the production technologies of microwave printed circuit boards.
