| 摘 要： | 利用WAXD研究PEKK的晶型，得到两种晶型其点阵常数（nm）为：I型a=0．775,b=0.609，c=101及II型a=0．418，b=1.13，c=1.007;表明多晶型不仅与结晶条件也与分子结构有关改变分子结构，在二氯乙烷中结晶都可将两种晶型完全分开对PEKK低聚物在二氯乙烷中结晶样品的研究证实了上述晶到

| Abstract: | Polymer PEKK characterized by WAXD has polymorphisms-crystal form I with crystal unit cell parameters of a= 0.755nm, b =0.609nm, c = 1. 101nm and crystal form II of a =0.418nm, b =1.414nm,c=1.007nm. Results of PEKK oligomers crystalized in solvent of C2H4Cl2 further prove above WAXD resuIts. Polymorphisms in thesc oligomers vary with both crystalizing condition and their molecular structure.Thus, by varing their molecular structure and crystalizing condition in C2H4Cl2, the two kinds of crystalforms in PEKK can be separated. |
