摘要： 选取分子主链中含有间位结构的聚芳醚酮低聚物为研究对象,利用TEM技术,发现这类低聚物晶体中存在一种新的四角叶片状单晶,此单晶的四角对角线夹角为101.9°,与从晶胞参数计算所得的102.6°一致,从而直观地证明这类含间位结构聚芳醚酮的晶胞按(110)面生长,球晶按b轴方向生长.

关键词: 含间位联结的聚芳醚酮, 低聚物, 四角叶片状单晶

Abstract: The crystal morphology of low molecular weight poly(aryl ether ketone)s containing metaphenyl links has been investigated by TEM techniques. Results show that there exists a new crystal morphology in the polymer crystallites, that is quadrant angular leaflike single crystals, the angular degrees between the two diagonals of which are 101.9° , which is in good agreement with the 102.6° obtained from the calculation of unit cell crystal parameters. The above morphology has directly shown that these kinds of poly(aryl ether ketone)s containing metaphenyl links has its crystal unit cell growing along the (110) crystal face while its spheruletics grow along its crystal b axis.

Key words: Poly(aryl ether ketone)s containing metaphenyl links, Oligomers, Quadra angular leaflike single crystals
