ABSTRACT:
High temperature thermosetting resin compositions which may be used as a polymer matrix for a printed circuit board will comprise a terpolymer of an ethylenically monosubstituted unsaturated monomer in which said substituent is an aromatic moiety such as styrene, an ethylenically alpha,beta-disubstituted unsaturated monomer in which each substituent is an aromatic or benzylic moiety such as acenaphthylene and a glycidyl ester of a monoethylenically unsaturated acid such as glycidyl methacrylate cross-linked with a copolymer of an anhydride of a dibasic olefinic acid such as maleic anhydride and an ethylenically monosubstituted unsaturated monomer in which said substituent is an aromatic moiety such as styrene.
