Sur la distribution des masses moléculaires dans les polyéthylène «Haute Pression»

Abstract: R E S U M E :On a applique aux polydthylbnes (( Haute pression D le procedd classique de la precipitation fractionnde. Ce procddB semble 1 la fois le plus simple et le plus efficace, 21 condition d'ernployer un prdcipitant dnergique (polytthylbneglycol) qui permet d'obtenir une d6mixtion de la solution en deux phases liquides (coacervation).A l'aide de fractions relativement homogBnes obtenues par des precipitations r6pet6es (fractionnement (( en triangle ))), nous avons dtabli une relation de la forrne classi… Show more
