The hydroxyl groups were introduced by adding one 2-(trimethylsiloxy)ethyl methacrylate (TMSEMA) unit at one or at both ends of the polymer chain. Theends were converted to 2-hydroxyethyl methacrylate (HEMA) units after the polymer-ization by acid-catalyzed hydrolysis. Gel permeation chromatography (GPC) in THFand proton nuclear magnetic resonance (1H-NMR) spectroscopy in CDCl3were used todetermine the molecular weight and composition of the polymers. These mono- anddifunctional methacrylate polymers can be covalently linked at the hydroxy termini toform star polymers and model networks, respectively.||ISSN:||2642-4169||DOI:||10.1002/(SICI)1099-0518(19990601)37:11<1597::AID-POLA5>3.0.CO;2-X||Rights:||© Wiley||Type:||Article||Affiliation :||University of Manchester Institute of Science and Technology|
