摘要
对 4 ,4 -二氯二苯砜进行磺化改性制得磺化二氯二苯砜 ,不同比例的 4 ,4 -二氯二苯砜和磺化二氯二苯砜与含二氮杂萘酮结构的类双酚单体 ( DHPZ)及 4 ,4 -二氟二苯酮共聚合制得不同磺化度的磺化聚醚砜酮 .对磺化单体及聚合物进行了 IR和 1 H NMR表征 ,并研究了聚合物的溶解性和成膜性能 .
Dichlorodiphenylsulfone(DCDPS) was sulfonated in fuming sulfuric acid. Poly(phthalazinone ether sulfone ketone)s were synthesized from 4-(4-hydroxyphenyl)-1-phthalazinone(DHPZ), 4,4-dichlorodiphenylsulfone, sulfonated 4,4-dichlorodiphenylsulfone(SDCDPS) and 4,4-diflorodiphenylketone(DFDPK) in the presence of potassium carbonate in sulfolane. High molecular weight polymers with different degrees of sulfonation were obtained with intrinsic viscosities between 0.86 and 1.21 dL/g. The structure of sulfonated 4,4-dichlorodiphenylsulfone was confirmed by FTIR and 1H NMR. Polymers containing sodium sulfonate groups were characterized with IR and 1H NMR. The solubilities of the polymers were studied.
