    • A method to prepare a bioactive polymer by covalently binding at least one amino group containing ligand to at least one polymer containing a plurality of free hydroxyl groups, said method comprising the following steps: (i) reacting the at least one polymer with an appropriate activating agent; (ii) reacting the resultant activated polymer in aqueous solution with desired amino group containing ligands; (iii) blocking by reaction or removing by hydrolysis residual polymer bound-ligand unreacted, activating groups; and wherein the said activating agent and/or leaving by-products formed by step (i) and/or by step (ii) and/or by step (iii), are swelling agents of the support polymer.
    • 通过将至少一个含氨基的配体共价结合至至少一种含有多个游离羟基的聚合物来制备生物活性聚合物的方法,所述方法包括以下步骤:(i)使至少一种聚合物与合适的活化剂 剂; (ii)使所得活化聚合物在水溶液中与所需含氨基的配体反应; (iii)通过反应或通过水解残余聚合物结合的配体未反应的活化基团进行封闭; 并且其中所述活化剂和/或离开由步骤(i)和/或通过步骤(ii)和/或通过步骤(iii)形成的副产物是载体聚合物的溶胀剂。
