Abstract: The copolymers possessing hydroxy and carboxyl groups were synthesized by saponifying the copolymers of vinyl acetatg and triallyl isocyanurate, and the effect of different degree of cross-linked copolymers on the saponification was investigated. Pore structure parameters and swelling capacity of these saponified copolymers were also determined. The saponified copolymers were used as the stationary phase in gas chromatography. Their gas chromatographic properties are preliminary evaluated.

Key words: Saponified copolymer, Saponification, Stationary phase in gas chromatography, Pore structure parameter
