Abstract in another language

A novel series of poly(p-xylylene) homopolymer and copolymers containing thermally cross-linkable cyclohexenyl moiety are prepared via base-catalyzed Gilch route to yield high-molecular-weight polymers. The resulting polymers are highly soluble in a wide range of organic solvents and could be solution cast into flexible and transparent films. The polymers are thermally stable up to 350 degrees C and the glass transition temperature (Tg) is in the range of 136 - 250 degrees C. They undergo thermal cross-linking via the cyclohexenyl moiety. The cross-linked polymer exhibits a high Tg of 294 degrees C, a low coefficient of thermal expansion (CTE) of 45 ppm K-1. A low dielectric constant of 2.5 and a very low dielectric loss tan d of 0.0004 at 1 GHz are obtained, which are superior to conventional interconnect polymers.
