摘要
用凝胶渗透色谱仪（ＧＰＣ）在一定条件下，测定聚合物的分子量及其分布的变化可以预示聚合物的最佳合成条件．同时，用ＦＴＩＲ和１ＨＮＭＲ表征了环氧封端酚酞型Ｃａｒｄｏ聚芳醚腈（ＥＴＭＰＣＥ）的分子链结构，测定了ＥＴＭＰＣＥ试样的环氧值和溶解性．
The changes of molecular weight( M n ) and molecular weight distribution (MWD coefficient) determined with GPC unde given conditions may betoken whether the reactive condition is optimum one.The epoxy terminated 2′,5′,2″,5″ tetramethylphenolphthalein poly(cyanoarylether)(E TMPCE) were also characterized by FT IR and 1 H NMR spectra,the epoxy value(E *) and the solubility of the E TMPCE samples were also measured.
