FLAME RETARDANT THERMOSETTING RESIN COMPOSITION WITH EXCEPTIONAL ELECTRICAL PERFORMANCE AT HIGH FREQUENCIES AND ELECTRICAL LAMINATE MADE THEREFROM.

摘要

The present invention relates to thermosetting resin compositions with excellent electrical properties comprising (a) a first vinyl ester resin synthesized from diglycidyl ether of bisphenol A and glacial methacrylic acid, in about 1 percent to about 95 percent by weight of the total composition; (b) a resin selected from the group consisting of (1) a second different vinyl ester synthesized from diglycidyl ether of bisphenol A with glacial methacrylic acid, and (2) an unsaturated polyester, in about 1 percent to about 69 percent by weight of the total composition; and electrical laminates made therefrom which further comprise a catalyst in about 0.1 percent to about 2 percent by weight of the total composition and which may or may not be clad with an electrical conductive layer on al least one side; and method of producing these.
