摘要： 应用一维电子密度相关函数方法,对含不同联苯结构的PEEKK-PEBEKK共聚物样品小角X射线散射(SAXS)去模糊强度分析计算表明：PEEKK-PEBEKK共聚物的聚集态结构明显地依赖于共聚物中联苯含量。当联苯含量nb=0.35时,积分不变量Q,长周期L,平均结晶片层厚d,电子密度差ηc-ηa和结晶度Wc,x值为最小,比表面积Os为最大。

Abstract: Structural studies of poly(ether ether ketone ketone) and poly(ether biphenyl ether ketone ketone) copolymers by means of SAXS and one dimensional electron density correlation function methods revealed that the structure of the aggregated state of copolymers depended closely on the biphenyl content(nb) in the copolymers. When nb=0.35,the invariant Q,long period L,average crystal lamellae d and electron density difference ηc-ηa(obtained by SAXS analysis) and the degree of crystallinity Wc,x gave minimum values, but the specific inner surfaces Os possessed maximum values.

Key words: poly(ether ether ketone ketone), poly(ether biphenyl ether ketone ketone), copolymer, SAXS, structure
