- Abstract
- <jats:title>ABSTRACT</jats:title><jats:p>The dynamic mechanical properties of supramolecular associative polymer networks depend on the average number of entanglements along the network‐forming chains, <jats:italic>N</jats:italic><jats:sub>e</jats:sub>, and on their content of associative groups, <jats:bold><jats:italic>f</jats:italic></jats:bold>. In addition, there may be further influence by aggregation of the associative groups into clusters, which, in turn, is influenced by the chemical structure of these groups, and again by <jats:italic>N</jats:italic><jats:sub>e</jats:sub> and <jats:bold><jats:italic>f</jats:italic></jats:bold> of the polymer. Therefore, the effects of these parameters are interdependent. To conceptually understand this interdependency, we study model networks in which (a) <jats:italic>N</jats:italic><jats:sub>e</jats:sub>, (b) <jats:bold><jats:italic>f</jats:italic></jats:bold>, and (c) the chemical structure of the associative groups are varied systematically. Each network is probed by rheology. The clustering of the associative groups is assessed by analyzing the rheological data at the end range of frequency covered and by comparison of the number of supramolecular network junctions with the maximum possible number of binary transient bonds. We find that if the total number of the network junctions, which can be formed either by interchain entanglement or by interchain transient associations, is greater than a threshold of 13, then the likelihood of cluster formation is high and the dynamics of supramolecular associative polymer networks is mainly controlled by this phenomenon. © 2019 Wiley Periodicals, Inc.
