  • Title: The identification of synthetic homopolymer end groups and verification of their transformations using MALDI-TOF mass spectrometry.
    Author: Li Y, Hoskins JN, Sreerama SG, Grayson MA, Grayson SM.
    Journal: J Mass Spectrom; 2010 Jun; 45(6):587-611. PubMed ID: 20527028.
    Abstract:
    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.
