Benzocyclobutenes (BCBs) are a family of thermally poly- merisable monomers for high-performance polymers, which have been widely used in the microelectronics industry because of their low dielectric constant, low dispersion factor, low water up-take, high thermal and chemical stability, and ease of processing.1 Homopolymers and copolymers of aryl bridged bisbenzocyclobutene monomers (bisBCB) also exhibit excellent properties.2 However, a practical method for ...
