| 摘要 |
The invention relates to arylacetylene polymers and thermoset resins prepared therefrom. The preferred thermoset resins are prepared by copolymerizing a polyacetylenically unsaturated prepolymer with about 2 to 70% of a monomeric acetylenically unsaturated aromatic compound that has a melting point below about 185 DEG C. and a boiling point above about 250 DEG C. The polyacetylenically unsaturated prepolymer is a polymer of at least one polyacetylenically substituted aromatic compound such as a diethynylbenzene, which prepolymer has a number average molecular weight of about 900 to 12,000 and contains about 5 to 20% by weight of acetylenic groups. Typical monomeric acetylenic aromatic compounds that are copolymerized with the prepolymer are diphenylacetylene and diphenylbutadiyne.
