Abstract
La relation [n]=7,53•10 −6 •M 0,98 est etablie entre la viscosite intrinseque du polyfumarate en solution dans le benzene a 30 o C et sa masse moleculairie pour M<3•10 5 . La valeur de a obtenue (0,98) est la plus elevee obtenue pour un polymere vinylique; elle diminue lorsque la masse moleculaire augmente et depend de la nature des groupes alkyl (0,87 pour le poly(fumarate de diethyle))
