Entanglement, involving one or more macromolecular chains, of duration at least equal to the period of observation.
Note: A volume element, in which the chains of two or more macromolecules are entangled, acts as a temporary junction point of a transient polymer network, such as can occur in a semi-dilute solution or a concentrated solution.
