## Abstract In the present paper, homologous series of polystyrenes, poly(styrenesulfonic acid)s and their corresponding sodium salts in a mass range between 2000 and 100000 Dalton were used as model systems, to check for the significance of matrix assisted laser desorption ionization time of fligh
## Abstract **Summary:** Three HECs with a high __MS__ (HEC 1: 1.89, HEC 2: 1.94, HEC 3: 3.03) were analyzed with respect to their substituent distribution and tandem reaction in the glucosyl unit by GLC of the corresponding glucitol acetates, and along the polymer chain by MALDIβToFβMS after a mul
Polystyrenes containing up to about 20 mol % sulfonic acid are reproducibly and readily prepared by the sulfonation of polystyrene at 50Β°C with acetyl sulfate in 1,2-dichloroethane solution. The metal salts of sulfonated polystyrene possess extremely high melt viscosities and are soluble in single s
