摘要：

Mixtures of styrene-methyl methacrylate copolymers and poly(methyl methacrylate), styrene-ethyl methacrylate copolymers and poly(ethyl methacrylate), styrene-butyl methacrylate copolymers and poly(butyl methacrylate), and an ethyl methacrylate-butyl methacrylate copolymer (1:1) and its homopolymers, were separated by liquid adsorption chromatography according to their compositions. Silica gel of 30 angstrom pore size was used as the stationary phase and mixtures of 1,2-dichloroethane and ethanol were used as the mobile phases. The composition of the mobile phase was regulated by gradient elution. An ultraviolet absorption detector at 233 nm was used to detect the copolymers and the homopolymers in the effluent.
