Abstract

For any polymer the determination of the average molecular weight and its distribution is an important part of characterising its physical properties. We report values for the Mn, Mw and dispersity, determined using gel permeation chromatography, of a neutral precursor polymer to poly(p-phenylenevinylene) in relation to polymerisation conditions. We have observed a maximum Mn value of approximately 100,000 with a dispersity of 5.7 and compare this value to that calculated for the "effective conjugation length", that is the number of repeat units over which uninterrupted π-electron delocalisation actually takes place, in fully converted poly(p-phenylenevinylene). © 1993.
