Abstract
This invention relates to a novel process for preparing vinylsilane-BCBs (vinylsilane-benzocyclobutenes) comprising reacting a hydrosilating reagent with an acetylene-BCB in the presence of a catalyst. The invention also relates to a novel mixture of isomers of DVS-bisBCB (1,3-divinyl-1,1,3,3-tetramethyldisiloxane bisbenzocyclobutene) as well as novel partially or fully cured polymers derived from the vinylsilane BCBs.
