Abstract
the method of 1H and 13C NMR analysis has been used to investigate reaction mixtures formed in the synthesis of oligoarylene sulphonoxides from the sodium salt of diphenylolpropane and dichlorodiphenylsulphone. A quantitative study was carried out to determine the amount of different endgroups and of monomeric and “dimeric” products formed at some stages in the synthesis. Number-average molecular weights were determined for oligoarylene sulphonoxides in the reaction mixture.
