Abstract (en)
[origin: EP0000385A1] This invention relates to poly(arylacetylene) thermosetting compositions and thermoset resins prepared therefrom. The thermosetting compositions comprise a poly(phenylene oxide) and a polycetylenically unsaturated prepolymer of a polyacetylenically substituted aromatic compound such as diethynylbenzene. The prepolymer has a number average molecular weight of about 900 to about 12,000 and contains from about 5 to about 20% by weight of terminal acetylenic groups. A representative poly(phenylene oxide) is poly-(2, 6-dimethyl-1, 4-phenylene oxide).
