It is well established that complex polymers such as block-and graft copolymers with incompatible components form self-assembled structures in bulk. These multiphase periodic structures are known to change their morphologies depending on molecular parameters such as molecular weight, compositions of component polymers and chain connectivity etc. Firstly, bulk structures of ABCA tetrablock polymers have been investigated and found that asymmetric structures was formed by this copolymer molecule. Secondly, morphological features of cyclic block copolymers has been studied. It was found that the chain dimension along the longitudinal direction for a cyclic block copolymer is quantitatively smaller than that of a linear triblock copolymer molecule with the same molecular weight.

众所周知，复杂的聚合物，如嵌段和接枝共聚物与不相容的组分形成自组装结构的本体。这些多相的周期性结构是已知的改变其形态取决于分子参数，如分子量，组成的聚合物和链连接等。首先，本体结构的ABCA四嵌段聚合物已被调查，发现这种共聚物分子形成的不对称结构。其次，研究了环状嵌段共聚物的形态特征。发现环状嵌段共聚物的链尺寸沿着纵向比具有相同分子量的线性三嵌段共聚物分子的链尺寸小。
