基质辅助激光解吸/电离飞行时间质谱（MALDI-TOF MS）的分辨能力的最新进展，使线性均聚物的详细表征，特别是提供宝贵的数据，确定其端基功能。随着大分子偶联反应在构建复杂聚合物结构中的重要性日益增加，准确监测端基转化的能力对于合成聚合物化学家来说变得越来越重要。本教程演示了MALDI-TOF MS在确定线性均聚物的端基官能度及其转换中的应用。聚己内酯和聚苯乙烯的例子进行了检查，并给出了各种方法的优点和缺点的数据分析。版权所有（C）2010约翰威利父子有限公司
Recent advances in the resolving power of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) enable the detailed characterization of linear homopolymers, and in particular provide invaluable data for the determination of their end-group functionalities. With the growing importance of macromolecular coupling reactions in building complex polymer architectures, the ability to accurately monitor end-group transformations is becoming increasingly important for synthetic polymer chemists. This tutorial demonstrates the application of MALDI-TOF MS in determining both end-group functionalities and their transformations for linear homopolymers. Examples of both polycaprolactone and polystyrene are examined, and the strengths and weaknesses of various approaches to data analysis are given. Copyright (C) 2010 John Wiley & Sons, Ltd.
