Theory of polymer blends

Research output: Contribution to journalConference articlepeer-review


The authors have applied their polymer RISM theory of blends to the case of a thermal and isotopic mixtures. It was found that in both of these mixtures, the chi parameter has significant noncombinatorial entropy of mixing contributions, which arise from chain connectivity and nonrandom packing. These composition fluctuations tend to signficantly stabilize the miscible mixture and thereby suppress the phase separation point. In general most polymer blends are influenced simultaneously by both structural and energetic effects, resulting in a combination of the two cases studied here.
