Abstract
A new cross-linking monomer, allyl-bis(benzocyclobuten-4-yl)methylsilane (ABCBMS), was synthesized and its physical properties were investigated. Copolymers of ABCBMS with triethylene glycol dimethacrylate (TGM-3) and bis(methacryloylethylene glycol) carbonate (BMCC-2) were obtained by photo- and thermal polymerization. The final cross-linking of the copolymers took place at 200 °C. Homo- and copolymers of ABCBMS, ABCBMS-TGM-3 (50: 50) and ABCBMS—BMCC-2 (50: 50) exhibit high thermal stability (Td5% = 460, 359, and 352 °C, respectively) and good dielectric properties (ε = 2.7–2.8 and tg δ = (3.7–6.7)•10−4 at 10 GHz).
