| Research Abstract |
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.
