HYDROXY-SUBSTITUTED ETHYNYLATED BIPHENYLS

摘要

A method is disclosed for making hydroxy-substituted ethynylated biphenyl compounds and for reacting such compounds with a family of noncross-linking thermosetting poly(arylene ethers) to produce novel poly(arylene ether) compositions which, when cured at glass transition temperatures greater than about 350 DEG C to form thin films, possess properties such as low dielectric constant, low moistures absorption, and high thermal stability. These films are suitable for use as intermetal dielectrics for multilevel interconnection.
