Tube diameter in tightly entangled solutions of semifiexible polymers

Research output: Contribution to journalArticlepeer-review

69 Scopus citations


The statistical mechanics of a confined polymer is presented. The calculations of the tube diameter and plateau modulus were based on two very different and complemetary descriptions of the interactions between a chain and its surroundings in an entangled polymer network. The binary collision approximation attempted to describe the motion of a test chain in a partially frozen environment where the surrounding chains are confined to static tubes and based upon a treatment of the nearby chain interactions.
