RESIN COMPOSITION FOR FORMING AN INSULATING LAYER OF A HIGHLY HEAT-RESISTANT ELECTRICAL WIRE, AND A HIGHLY HEAT-RESISTANT ELECTRICAL WIRE WITH EXCELLENT ABRASION RESISTANCE AND THERMAL RESISTANCE USING THE SAME

摘要

PURPOSE: A resin composition for a highly heat-resistant electrical wire is provided to be used at 250 °C or more while not containing a halogen atom, and to be suitable for an insulating layer of electrical wire requiring high heat-resistance, such as wound wire and electric wire for alternators.;CONSTITUTION: A heat-resistant resin composition for an insulating wire comprises a poly(diphenylamide benzobisimidazole) polymer. A repeating unit configuring the poly(diphenylamide benzobisimidazole) polymer has a structure of chemical formula 3 or 4. In chemical formulae, R1, R2, Rm and Rn are a functional group selected from the group consisting of hydrogen, C1-4 alkyl group, vinyl group, acryl group, methacryl group, and hydroxyl group, wherein the R1, R2, Rm and Rn are the same or different.;COPYRIGHT KIPO 2010
