Benzocyclobutene Resins Containing Olefinic Bonds and Preparing Methods Thereof

Abstract

The present invention provides benzocyclobutene resins containing olefinic bonds and preparing methods thereof, which relate to a technical field of high-performance resins. The resin structural formula of the present invention is: wherein R1, R2 and R3 are benzocyclobutenyls or hydrogen atoms, at least one of R1, R2 and R3 is a benzocyclobutenyl; R4, R5 and R6 are alkyls, vinyls or hydrogen atoms and are identical with each other; the preparing method thereof is to prepare the benzocyclobutene resin by reacting unsaturated resins of different molecular weights with halogenated benzocyclobutene through Heck reaction. The conditions for preparing the benzocyclobutene resin are mild and easy to produce, and the resin formed by ring-opening polymerizing and curing through further heating which has high crosslinking density, good heat resistance, good resin smoothness, and extremely low dielectric constant and dielectric loss performance, so it is a good photoelectric material.
