ABSTRACT:
The invention relates to poly(arylacetylene) thermosetting compositions and thermoset resins prepared therefrom. The thermosetting compositions comprise a polyacetylenically unsaturated prepolymer and a phenol-aldehyde resin. The prepolymer is a polymer of at least one polyacetylenically substituted aromatic compound, such as diethynylbenzene, and has a number average molecular weight of about 900 to about 12,000 and contains about 5 to about 20% by weight of terminal acetylenic groups. Typical phenol-aldehyde resins are the resoles and novolacs.
