Chain Entanglement in Polymer Melts and Solutions

Journal Article (Academic article)

We consider the problem of entanglement in polymer melts and solutions with no excluded-volume interactions (esolvent). A number of simple ideas on this subject, cast in the form of scaling theories, have recently been proposedintheliterature. Atfirstglancetheseideasare seeminglyunrelated.

Wewillshowthatthe differences between the scaling ideas arise because there are two independent length scales in the problem, which means that scaling must rely on a conjecture about the natureofentanglement. Wethenexamineexperimental data on polymer melts and solutions to test these ideas.
