Copolymers with, microphase separation were obtained. The structure of PEO phase domains changed from homogeneously dispersed sphere with regular interface to steric continuous network when the EO content reached 52.16%.

• PEG-g-PAn共聚物存在着微观相分离，并且当共聚物中的EO单元的摩尔含量增至52.；16%25时，PEO微区则从相畴界面规则、尺寸分布较均匀的球形结构变成连续的网络结构。
