To improve the effect of CDCA on dissolving cholesterol gallstone, the water-soluble copolymers as polycarboxylic acid of comb-like copolymers and C_(60)-PCC were synthesized, which being used for modification of CDCA and strengthening effects of CDCA on dissolving the cholesterol gallstones by their entropy-repelled properties of comb-shaped side chains in buffers of phosphate and in model bile.The design theory of polymer was mainly employed to synthesis the conjugate of PCC-CDCA and C_(60)-PCC-CDCA by C_(60), polyoxyalkylene allylalkyldiether and maleic anhydride, which were copolymerized with AIBN as initiator, and then PCC or C_(60)-PCC were reacted with CDCA. The structures of the copolymers and the conjugates of PCC-CDCA and C_(60)-PCC-CDCA were confirmed with IR, TLC and TEM. The dissolving effects and the dissolution kinetics mechanism of cholesterol gallstone was inverstigated in PBS and in model bile of different cholesterol saturated index at pH7.4, including PCC-CDCA or C_(60)-PCC-CDCA.
