An approach to the preparation of pullulan-graft-poly(2-methyl-2-oxazoline)s based on Cu-catalyzed azide-alkyne cycloaddition with polyoxazoline-azide was applied. All of the obtained polymers were characterized through classical molecular hydrodynamic methods and NMR. The formation of graft copolymers was accomplished by oxidative degradation of pullulan chains. Nevertheless, graft copolymers were obtained as uniform products with varied side chain lengths and degrees of substitution.
采用了一种基于铜催化的叠氮化物-炔烃环加成反应，以聚恶唑啉-叠氮化物制备支链淀粉接枝聚（2-甲基-2-恶唑啉）的方法。所有得到的聚合物均通过经典的分子流体动力学方法和核磁共振进行了表征。支链淀粉接枝共聚物的形成是通过支链淀粉链的氧化降解来实现的。然而，得到的接枝共聚物是具有不同侧链长度和取代度的均匀产物。
