Resumen: The e ffi cient, controlled polymerization of a batch of new poly(hydroxyethyl methacrylate- co -furfuryl methacrylate)s, [poly(HEMA- co -FMA)], of various compositions was achieved using atom transfer radical polymerization (ATRP) in methanol. When the FMA composition did not exceed the 10 mol% ratio, the evolution of molecular weight with conversion was linear, and polydispersities were around 1.1 for polymerization reactions at 15 C and around 1.3 – 1.4 at 25 C, indicating good control over the polymerization process. HEMA-based hydrogels were obtained by means of the Diels – Alder reaction between poly(HEMA- co -FMA) and an hydrophilic bisdienophile. Geli fi cation was monitored by di ff usion- fi ltered 1 H NMR and solution 1 H NMR spectroscopy. Modulated temperature di ff erential scanning calorimetry (MTDSC) suggests the thermo-reversibility of the Diels – Alder coupling reaction of HEMA polymeric networks. Rheological studies showed th...
