Title:
NORBORNENE-BASED POLYMER HAVING LOW DIELECTRIC CONSTANT AND LOW-LOSS PROPERTY, AND INSULATING MATERIAL, PRINTED CIRCUIT BOARD AND FUNCTIONAL ELEMENT, USING THE SAME
Document Type and Number:
Japanese Patent JP2010065206
Kind Code:
A
Abstract:
To provide a novel norbornene-based polymer having a low dielectric constant, low-loss properties and excellent processability and useful as a low-loss insulating material, and to provide an insulating material, a printed circuit board and a functional element, using the polymer.
The norbornene-based polymer includes at least one of repeating unit expressed by general formula (1). In the formula, at least one of R1 to R4 independently represents a substituted or unsubstituted linear or branched aralkyl group having 4 to 31 carbon atoms, and the rest of R1 to R4 each independently represents a hydrogen atom or a substituted or unsubstituted linear or branched 1-3 C alkyl group; and n is an integer of 250 to 400.
