A series of poly copolymers(P(CPP-SA))with different monomer proportions were synthesized via solid-liquid phase transfer catalytic method using 18-crown-6(18C6) as catalyst. The structures of P(CPP-SA)s were characterized by FT-IR and

H-NMR methods. The viscosity-average molecular weights of P(CPP-SA)s were calculated though the intrinsic viscosities. The reaction conditions were investigated that using 20% 18C6 after 15h the intrinsic viscosity of P(CPP-SA) reached to 1.2dL/g with the viscosity-average molecular weight was 2.02×10

. The in-vitro degradation tests of P(CPP-SA)s were carried out in phosphate buffer solution (pH=7.4). The results indicated that the degradation ratioes depended on the monomer proportions. When the CPP/SA was 50/50 (mol/mol)
the linear relationship between degradation ratio and degradation time was verified. The application of P(CPP-SA)(CPP/SA=50/50) was well promising.
