Abstract
The dynamic heterogeneities of miscible polymer blends were analyzed. The distribution of mobilities experienced by a probe monomer in a miscible blend of chains with disparate glass transition temperatures was found to be much broader than in pure polymers. It was found that concentration fluctuations yield distinctly different temperature dependences for the dynamics of the two different components.
