β poly DL asparamide was synthesized by polycondensation of DL aspartic acid and 85% phosphoric acid in vacuity at 180℃
and then by ring opening reaction with 2 aminoethanol together with crosslinking reaction with 1
4 butanediamine. The swelling behavior of the gel in several solutions was investigated.The result shows that the swelling ratio of the gel in distilled water is 110~440
and it decreases differently in different concentration of electrolyte solutions.The swelling ratio in 0.16 mol/L 5-Fu solution can reach 140.Effect of molecular weight of polysuccinimide、amount of solvent and crosslinking agent on the swelling behavior of the gel was also studied.
