Two novel bis-benzocyclobutene-terminated monomers containing ether structure, BCB-1 and BCB-2
were synthesized by the nucleophillic reaction between 4-bromobenzocyclobutene and bisphenol A or N,by using cuprous chlorine as catalyzer. The cure behavior and processability of the two monomers were evaluated by DSC and rheometer. After curing,the thermal stability and dielectric properties of these cured resins were also investigated. The experimental results indicate that these monomers possess excellent processability,and that the cured resins derived from
them have good thermal stability and outstanding dielectric properties.
