A class of thermosetting resins, prepared from triethynyl benzene, diethynyl phenylether and phenylacetylene, called ATP resins has been found useful as a glass-filled composite which can be laminated and used for the fabrication of printed circuit boards. The structure of this resin is a highly crosslinked complex structure produced by the coupling of free ethynyl groups. It is prepared by the following series of reactions: This partially polymerized product can be thermally crosslinked to an insoluble infusable polymer.
