摘要
在合成了二种具有相同组成不同嵌段结构排布的共聚物基础上对它们溶液的物理化学行为用荧光探针的方法进行了研究，结果表明：由于结构排布的不同其物理化学行为有着较大的差异，三嵌段结构的共聚物较二嵌段者更易于形成胶束体系，而二嵌段共聚物则易于发生凝胶化，对上述结果进行讨论和解释．
Two kinds of poly (ethylene oxide) and poly (propylene oxide) diblock and triblock copolymers which have the same compositions but different block architecture have been synthesized in this work.The association properties of them were studied by fluorescence methods in aqueous solution.It was found that the copolymers with different block architecture have different properties.The triblock copolymer is easier to form micelles than the diblock copolymer in aqueous solution.But gelation is easier for the diblock copolymer than for the triblock copolymer.The results were explained and discussed preliminarily..
