摘要

POLYGLYDICYLPHENYL ETHERS OF ALKYLENE OR ALKYLEOXY CHAINS FOR USE IN MICROELECTRONICS ADHESIVES ABSTRACT OF THE INVENTION This invention relates to flexible epoxy resins characterized by a low ioniccontamination, total chlorine content less than 0.1%. The epoxy resins are liquids atroom temperatur, have Tg values when cured of less than or equal to 150[err]C, haveneat resin viscosities of 25,000 cps or less at 25[err]C, and have a structural compositioncomprising an oligomeric backbone of alkylene or alkyleneoxy repeat units, terminatedwith an aromatic moiety bearing one or more epoxy functionalities.
