摘要
应用基质辅助激光解吸电离质谱技术对新型环状聚芳酯预聚体进行了表征，从而确 定了该环状聚合物不同聚合度（ｎ＝１，２……８）的存在，获得了满意的结果。实验证明本方法 是测定环状聚合物不同聚合度快速、有效、准确的方法。
The macrocyclic polyarylate oligomers have been studied by matrix-assisted laser desorption ionization mass spectrometry (MALD-MS) and the existence of oligomers with different degrees of polymerization (n = l,2…… .8) has ho proved satisfactorily. The experiment result shows that MALDMS technique is a rapid, effective and accurate tool to determine the degree of polymerization in macrocyclic oligomers.
