This document specifies a general method for determining the average molecular mass and molecular mass distribution of polymers (see Reference [1]) from 2 000 g \u00b7 mol-1 to 20 000 g \u00b7 mol-1 by matrix-assisted laser desorption\/ionization time-of-flight mass spectrometry (MALDI-TOF-MS).<\/p>\n

The average molecular masses and molecular mass distributions are calculated from a calibration curve constructed using synthetic-polymer and\/or biopolymer standards. This method is therefore classified as a relative method.<\/p>\n

The method is not applicable to polyolefins or to polymers with a polydispersity >1,2.<\/p>\n","protected":false},"excerpt":{"rendered":"
