英文摘要This paper presents a feasible method for introducing crosslinkable groups into a polymer to achieve excellent chemical resistance and improved thermal stability. here, 3,6-bi(4-fluorobenzenzoyl)-n-allylcarbazole, a novel allyl-containing difluoroketone monomer, is synthesized and characterized. the resulting monomer is polymerized with phenolphthalein through the aromatic nucleophilic substitution reaction at 160 degrees c to provide the soluble poly(aryl ether ketone) (paek) with a pendant allyl group. the obtained paek is characterized using fourier transform infrared spectroscopy, nmr and gel permeation chromatography. the crosslinking reaction of the polymer occurs at 270 degrees c, and it imparts excellent solvent resistance. dsc analysis shows that the glass transition temperature (t-g) of the cured polymer increases to 262-306 degrees c when the curing temperature is elevated or when the curing time is extended within certain limits. the rate of increase of t-g and the rate of the crosslinking reaction decrease as the curing time is extended under all of the investigated curing temperatures. the cured paeks possess good thermal stability with 5% weight loss temperatures up to 450 degrees c. the tensile strength and young's modulus of the polymer film cured at 300 degrees c for 2h are 65 mpa and 1.4 gpa, respectively. in addition, the polymer films before and after curing exhibit similar uv-visible absorption and blue light emission.
