适用范围：This International Standard specifies a general method for determining the average molecular mass and molecular mass distribution of polymers from 2000 g mol 1 to 20000 g mol 1 by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI TOF MS). 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. The method is not applicable to polyolefins or to polymers with a polydispersity > 1,2.
