Solubilization of hydrophilic saccharide chains into organic solvents has been attempted by incorporating saccharide‐substituted styrene unit into polystyrene main chain. Lactose‐, maltopentaose, and amylose‐substituted styrene monomers were copolymerized with styrene. Resulting chloroform‐soluble copolymers were characterized, and structural formation was investigated. Copolymers of lactose‐substituted styrene and maltopentaose‐substituted styrene with styrene were dissolved into chloroform. The chloroform‐soluble polymers contained about 12 disaccharide lactose chains or 1.7 maltopentaose chains as the pendant groups in one polystyrene molecule. Chloroform‐insoluble methyl orange was dissolved into chloroform with the help of chloroform‐soluble polystyrene having some saccharide chains. On the other hand, when an amylose‐substituted styrene unit was inserted in a polystyrene chain, the resulting polymer became insoluble into chloroform. Amylose polysaccharide of DP n = ∼24 was not dissolved into chloroform by this method.
