Transient networks by hydrogen bond interactions in polybutadiene-melts

Abstract

Transient networks are intermediate between covalently crosslinked networks and entangled polymer melts. The linkages between polymer chains are formed by secondary valence interactions. As a consequence, transient networks may have properties of both extreme cases. The questions of equilibrium network properties and dynamic properties in relation to the network structure are of special interest for the understanding of these systems. To study structure-property relationships in transient networks, polybutadienes with few functional groups, that form hydrogen bond complexes, are used as model system.
