Abstract: A method is proposed to separate styrene homopolymer from polydimethylsiloxane-g-poly-styrene and to determine their contents by quantitative SEC with Porasil column and mixtureof 1:5 tetrahydrofurane-cyclohexane.

Key words: size exclusion chromatography, polydimethylsiloxane-g-polystyrene
