title: Polymer segmental cross correlations from dielectric relaxation spectra of block copolymers.
abstract: Dielectric relaxation spectra of solutions of block polymers containing sequential type-A dipoles are considered from a theoretical correlation-function standpoint. Spectra of a specific set of block copolymers can be combined to isolate the dynamic cross-correlation between the motions of two distinct parts of the same polymer chain. Unlike past treatments of this problem, no model is assumed for the underlying polymer dynamics.
