PREPARATION OF A BENZOCYCLOBUTENE-BASED POLYMERIC BINDER FOR THE MANUFACTURE OF MICROWAVE-RANGE MATERIALS

A new copolymer based on benzocyclobutene-4-yl vinyldimethylsilane was developed and synthesized for application in printed circuit board manufacturing. The influence of copolymer composition on the viscosity of its solutions in mesitylene was established, and concentration dependences of viscosity were obtained. The possibility of using solutions of the benzocyclobuten-4-yl vinyldimethylsilane copolymer as a binder in the production of prepregs for the production of fiberglass was demonstrated. The dielectric properties of the obtained fiberglass make it possible to recommend it for use in microwave printed circuit board technologies.
