Abstract

We report on polarized and depolarized dynamic light scattering (DLS) measurements on two asymmetric poly(ethylene-alt-propylene-block-dimethylsiloxane (PEP-PDMS) diblock copolymers in bulk. Apart from the disordered phase, the samples form various ordered morphologies below their respective order-to-disorder transition temperatures: One of the samples forms the hexagonal structure composed of PEP cylinders in a PDMS matrix, whereas the other one forms three ordered structures as a function of temperature, among them two cubic micellar structures and a non-cubic structure. We report here on the dynamic processes found in polarized DLS measurements in the disordered, hexagonal, cubic micellar and non-cubic structure in the Same material.
