✦ Synopsis
Quasi-&&c hght scrrttermg euperrments %rth NaPSS of M,, = 7.8 X lo5 g mot-r @fJMrr C l.tO> m aqueous sofutions 0.01 hI m NaCi have been Performed at nine drfferent polymer concentrations. From the angular dependence of the average decay rate of the rntensrty aut_ocorrehrtron functron, effectrve tra.nshttronal drffusron coeffinentsireff were obtamed. The concentration dependence of Deff is rn good agreement wrth the theorettcal predrctions based on en apphcatron of the scahng approach to polyefectrolyte soluttons.
