Molecular weight distribution of fractionated poly (hexamethylene Oxide)

Abstract

Poly(hexamethylene oxide) obtained by two routes, polycondensation and cationic polymerisation, is fractionated and its molecular weight distribution is analysed by using well known data treatment methods namely those of Beall, Wesslau, Tung and Saiz and Horta. The results are compared and discussed showing that the polycondensated sample has a lower molecular weight and wider distribution than the cationic one.
