J. Xu et al., A NEW THEORETICAL FORMULA FOR THE DETERMINATION OF THE COPOLYMER COMPOSITION DISTRIBUTION MEASURED BY GEL-PERMEATION CHROMATOGRAPHY, Macromolecular rapid communications, 18(7), 1997, pp. 601-607
A new theoretical formula, used for the determination of the chemical
composition distribution of copolymers, is proposed in this paper. The
composition distribution of styrene in chlorinated butyl rubber/polys
tyrene comb graft copolymer was obtained by gel permeation chromatogra
phy utilising a combination of refractive index and ultraviolet detect
ion. It is a more convenient and time-saving method for the characteri
zation of the molecular structure parameters of a copolymer compared t
o the conventional experimental method.
