- 摘要： A phthalazinone monomer with an allyl group, i.e. 4-(3-allyl-4-hydroxyphenyl)phthalazin-1(2H)-one, was synthesized and then copolymerized with 4-(4-hydroxylphenyl)(2H)-phthalazin-1-one and 2,6-diflurobenzonitrile by means of aromatic nucleophilic polycondensation to provide a series of crosslinkable poly(aryl ether nitrile)s. The virgin copolymers exhibited good solubility in polar organic solvents with relative high molecular weights (Mw: 45,130-58,403, inherent viscosities: 0.58-0.75 dL/g). After cross-linking, the thermal stability and solvent resistance of the polymer increased. (C) 2014 Xi-Gao Jian. Published by Elsevier B.V. on behalf of Chinese Chemical Society.
