Molecular weight parameters for synthetic polymers are defined and their determination by matrix-assisted laser desorption/ionization (MALDI) is described. In particular, details of matrix materials that are suitable for this type of measurement are provided. The availability of increased instrumental resolution provides a simple means of endgroup identification for some synthetic polymers.
