Described are sample preparation and chromatographic methods of analysis that enable the determination of the weight fraction sol rubber and the molecular weight distribution of the sol fraction rubber. These quantities, when combined with knowledge of the starting molecular weight distribution of the rubber, enable characterization of the extent of crosslinking and the extent of chain scissioning in the rubber domains of acrylonitrile-butadiene-styrene (ABS) copolymers. These structural attributes affect the physical properties of ABS resins.
