NORBORNENE-BASED POLYMER WITH LOW DIELECTRIC CONSTANT AND LOW-LOSS PROPERTIES, AND AN INSULATING MATERIAL, A PRINTED CIRCUIT BOARD AND A FUNCTIONAL ELEMENT USING THE SAME

摘要

PURPOSE: A norbornene-based polymer is provided to ensure low dielectric constant, low loss property, and excellent processability, and to be used as a low loss dielectric in an embedded substrate or functional element.;CONSTITUTION: A norbornene-based polymer has at least one kind of repeating unit represented by chemical formula 1. In chemical formula 1, at least one of R1-R4 is substituted or unsubstituted C4-C31 linear or branched arylalkyl group, the others of R1-R4 are independently hydrogen or substituted or unsubstituted C1-C3 linear or branched alkyl group; and n is an integer of 250-400.;COPYRIGHT KIPO 2010
