Static scattering from cyclic copolymers in solution

M. Benmouna , R. Borsali , H. Benoît

The static scattering properties of cyclic diblock copolymers in solution are studied. The case of a symmetric diblock in a solvent satisfying the optical theta condition is considered in details. The results show substantial differences with respect to linear diblock copolymers. The additional entropic interaction in cyclic chains induces a decrease of the scattering intensity and a shift of the location of its maximum to a higher q value. This results in a substantial compatibility enhancement as compared to linear copolymers.
