title: Gel permeation chromatography of fullerene-centered macromolecules.
abstract: Gel permeation chromatography (GPC) behavior of fullerene-centered macromolecules is investigated. Because of the globular shape of the macromolecules, their GPC results are different from those of linear polystyrene standards. These macromolecules may serve as alternative molecular weight standards for polymers or dendrimers of similar globular structures. The results also show that the GPC analysis is capable of discerning relatively minor structural differences in the fullerene-centered macromolecules.
