    摘要: Enzymes are convalently found to anionic or cationic hydrophilic polymeric carriers formed by essentially complete reaction of pendent anhydride groups of ethylene-maleic anhydride copolymer (EMA) with a diamine selected from the group consisting of hydrazine, P, P'-diaminodiphenylmethane and 1,6-diaminohexane to produce resins having pendent amine groups. The EMA-hydrazide and EMA- P,P'-diaminodiphenylmethane resins can be rendered cationic by reaction with N,N-dimethyl-1,3-propanediamine.
