title: Gel content determination in cross-linked polyethylene.
abstract: Gel content is the dominating parameter which affects properties and prescribes the behaviour of a given type of cross-linked polyethylene. Researchers have determined the gel content by several methods based on solvent extraction, a process which dissolves the linear thermoplastic polymer but swells only the cross-linked fraction. In this work, a comparative evaluation was made using model samples to select the most effective solvents and the suitable extraction conditions leading to increased reliability.
