| 摘 要： | 以无水AlCl3/二氯乙烷(DCE)/N,N-二甲基甲酰胺(DMF)为复合溶剂体系,在低温条件下,以4,4’-二苯氧基二苯砜(DPODPS)、对苯二甲酰氯(TPC)、4,4’-联苯二甲酰氯(BPPC)为原料通过亲电共缩聚反应制得一系列聚芳醚砜醚酮酮(PESEKKs),用FT-IR、DSC、TG、WAXD等技术对聚合物做了表征.结果表明:随着BPPC含量的增加,共聚物的Tg从194 ℃上升到210 ℃,Tm从223 ℃增加到238 ℃,热分解温度均大于550 ℃,聚合物的耐热性能得到显著提升.经过检测,共聚物的溶解性能良好.

| Abstract: | Novel aromatic poly(arly ether sulfone ether ketone ketone)s(PESEKKs)were synthesized by electrophilic Friedel-Crafts solution copolycondensation of 4,4’-diphenoxy diphenyl sulfone(DPODPS)with a mixture of 4,4’-Biphenyldicarboxylic dichloride(BPPC)and terephthaloyl chloride(TPC)in the presence of anhydrous AlCl3 and N,N-Dimethylformamide(DMF)in 1,2-dichloroethane(DCE).The polymers obtained were characterized by different techniques such as FT-IR,DSC,TG and wide-angle X-ray diffraction(WAXD).The result indicates that the introduction of diphenyl moiety into the main chain improves the thermal stability,the polymers had high Tg of 194-210 ℃,moderate Tm of 223-235 ℃,and their thermal decomposition temperature was more than 550 ℃,which are adapted to the melt processing.Besides,the solubility of the polymer is good. |
