New controlled release systems produced by self-assembly of biopolymers and colloidal particles at fluid-fluid interfaces
Existing methods to obtain the primitive path network for monodisperse, linear polymers in the molten state are critically compared. A connection is established between the original "annealing" and newer geometrical approaches. A discrepancy of about 15% is observed in the mean primitive path length obtained by these methods for well-entangled polymers. This deviation is attributed to disentanglement that occurs during annealing. A number of well-equilibrated polymeric systems and some toy-configurations (rings) were studied to estimate the relative contributions of slip and constraint release by end-looping to the observed disentanglement. We found that about half (approximate to 7.7%) of the discrepancy persists for ring polymers in which end-looping is not possible, and may be attributed to slip alone. It is argued that the characteristics of the network obtained by annealing become practically equivalent to those obtained by geometrical methods in the asymptotic limit of small chain diameter and rapid quenching.
