摘要
应用自制的新型类双酚单体4-(4-羟基苯基)-2,3-二氮杂萘酮(DHPZ)与对苯二酚(HQ)成功地合成了新型共聚醚酮树脂COPPEK/HQ,对所得聚合物进行了性能表征,实验结果表明,此类聚合物较已经合成的新型杂环取代联苯型聚醚酮PPEK具有溶解性好,易于加工等特点,且耐温等级较高。
A series of novel copoly(heterocycl substituted arylketone) were successfully synthesized from hydroquinone, bis(4fluorophenyl) ketone and 4(4hydroxyphenyl) 2,3phthalazin1one with anhydrous potassium carbonate as catalyst. The synthesized polymers exhibited high glass transition temperature (about 200 ℃) together with excellent thermooxidatively stability. The sequential structure of synthesized polymers was studied and discussed by means of 13CNMR spectroscope and wide angle Xray diffraction technique.Depending on the experimental results, these asmade' copoly(heterocycl substituted arylketones) were found to show a long sequential molecular structure similar to a multiblock copolymer. They also exhibit good comprehensive properties, such as fair processability, solubility and high mechanical strength.
