Prepreg, Composite Magnetic Substrate, Substrate, Double Side Metal Foil-Clad Substrate, Flame Retardant Substrate, Polyvinylbenzyl Ether Resin Composition, Thermosetting Polyvinylbenzyl Ether Resin Composition, and Method for Preparing Thermosetting Polyvinylbenzyl Ether Resin Composition

摘要

A composite dielectric material comprising a resin resulting from a polyvinylbenzyl ether compound and a dielectric ceramic powder dispersed therein is useful in the high-frequency region. A composite magnetic material comprising a polyvinylbenzyl ether compound and a magnetic powder is also provided as well as a flame retardant material comprising a polyvinylbenzyl ether compound and a flame retardant. These materials may be used in the fabrication of substrates, prepreg sheets, coated metal foils, molded items, and metal foil-clad substrates.
