摘要: 根据Flory热力学统计理论和比容-熔融热作国法,由DSC结果得到了不同联苯含量的聚醚醚酮酮-含联苯聚醚醚酮酮(PEEKK-PEBEKK)共聚物的熔融热△Hf0,两种方法获得的△Hf0结果吻合。在此基础上给出了PEEKK-PEBEKK共聚物不同联苯含量的熔点计算表达式。结果还表明,随着联苯含量nB,的变化,△Hf0明显改变;当nB=0.35时,PEEKKPEBEKK共聚物的△Hf0值最小。

Abstract: on the basis of DSCmeasurements,the △Hf0 values of the fusion heat for PEEKK-PEBEKK copolymers with various biphenyl contents were obtained by using thermodynamics statistical theory proposed by Flory and graphical method of the specific volume-fusion heat.The results reveal that △Hf0 values determined by these two methods for PEEKK-PEBEKKcopolymers with various biphenyl content are nearly the same,and that △Hf0 values are closely dependent on biphenyl content.△Hf0 value is minimum at nB=0.35.
