Kurzfassung:
In this work, benzocyclobutene‐introduced poly(silmethylene)s were synthesized by ring‐opening copolymerization of benzocyclobutene (BCB) functionalized disilacyclobutene with phenyldisilacyclobutene. The incorporation ratio of BCB was tailored by changing feeding ratio of 1,3‐dimethyl‐1,3‐dibenzocyclobutene‐1,3‐disilacyclobutane and 1,3‐dimethyl‐1,3‐diphenyl‐1,3‐disilacyclobutane, thus enabling the control of ultimate properties of cured resins. With increasing the incorporation ratios of BCB from 9.5 to 28.9 mol%, T5% of cured resins is improved from 404°C to 462°C, while the dielectric constant is decreased from 2.59 to 2.41 at 10 MHz. The excellent thermal stability and low‐dielectric performance make such thermosets potential inter‐layered or inter‐lined low‐dielectric media. Copyright © 2017 John Wiley & Sons, Ltd.
