## Abstract The end groups of a sample of poly(methylphenylsilane) (PMPS) obtained by the Wurtz coupling reaction of diorganodichlorosilane were characterized by MALDIβTOF mass spectrometry. Three fractions were obtained by fractionation of a PMPS sample with methanol, in order to get information o

## Abstract The importance of proper conversion of MALDIβMS signals into the number of polymers with a certain mass increment (by taking into account a nonconstant conversion factor) is demonstrated with calculated SchulzβZimm and Poisson distributions. Measurements of two narrow polystyrene standa
Four samples of Ny6, each terminated by different end groups, i.e., diamino terminated, monoamino terminated (monocapped), dicarboxyl terminated, and amino-carboxyl terminated, were synthesized and analyzed by MALDI-TOF Mass Spectrometry, in order to accurately characterize their structure by direct
