Correlation effects in hydrogen-bonded polymer blends

In hydrogen-bonded polymer blends there are long range correlations that are a result of the combined covalent and hydrogen-bond connections. A mean field description of these mixtures is presented which indicates that there should be an infinite correlation length above some percolation threshold....

Zusammenfassung:	In hydrogen-bonded polymer blends there are long range correlations that are a result of the combined covalent and hydrogen-bond connections. A mean field description of these mixtures is presented which indicates that there should be an infinite correlation length above some percolation threshold. There are various consequences of the compositional heterogeneities or clustering that results from these effects and these are discussed in this paper.
