Περίληψη:
The role of molecular architecture in determining the phase behavior, morphology and material properties of nanostructured multigraft copolymers was analyzed. The conformational asymmetry between the block materials was the ratio of segmental volume to the square of statistical segment length for the block material. Branched block copolymers were found to be able to yield morphologies which could not be formed by the linear diblock copolymers at the same volume fractions. The results show that the thermoplastic elastomers (TPE) were widely used for SBS and triblock copolymers due to the thermal reversibility of crosslinks generated by the microphase separation of PS domains.
