Fecha de publicación: | 2013 | Editor: | Pergamon Press | Citación: | Carbohydrate Polymers 94: 755- 764 (2013) | Resumen: | The synthesis and characterization of amphiphilic polymers bearing gluconolactone moieties has been described. In a first step, an unprotected glycomonomer 2-[({[4-(d-gluconamid-N-yl)butyl]amino}carbonyl)oxy]ethyl acrylate, HEAG, has been synthesized. Posterior, this glycomonomer has been copolymerized with methyl methacrylate at different compositions and the kinetic behavior has been also studied calculating the monomer reactivity ratios by Kelen-Tüdös extended equation. In addition, the long side-chain crystalline behavior of these carbohydrate-based copolymers with high composition of glycomonomer has been examined by using conventional and modulated differential scanning calorimetry and X-ray diffraction measurements. At the same time, the phase separation behavior of carbohydrate-based copolymers with lower HEAG content has been determined by their glass transition temperature measurements. Finally, the thermal stability of all these amphiphilic copolymers has been evaluated by thermogravimetric analysis. © 2013 Elsevier Ltd. | URI: | http://hdl.handle.net/10261/95724 | DOI: | 10.1016/j.carbpol.2013.01.053 | Identificadores: | doi: 10.1016/j.carbpol.2013.01.053 issn: 0144-8617 e-issn: 1879-1344 |
