Abstract : The invention relates to a process for preparing a polyphenylene lacquer. A substantially void-free laminate or composite is provided that comprises a reinforcing material coated with a cured copolymer of polyphenylene and a polysulfonyl halide, the copolymer having been prepared by reaction in an alcohol-free chloroform medium and applied to the reinforcing material as a solution in the medium. It has been discovered that by conducting the reaction in alcohol-free chloroform, a thermosetting polyphenylene resin is produced that has superior molding characteristics as well as better wetting characteristics.
