Abstract

Este artículo describe la preparación de nuevos polímeros acrílicos sensibles a estímulos (pH ) derivados de la morfolina y pirrolidina usando agua como disolvente. Tres nuevos monómeros metacrílicos N-etil morfolina metacrilato (EMM), N-etil morfolina metacrilamida (EMA) y N-etil pirrolidina metacrilamida (EPA) han sido sintetizados mediante reacciones sencillas. Los correspondientes monómeros EMM, EMA y EPA fueron homopolimerizados en disoluciones de agua/isopropanol usando persulfato de amonio como iniciador radical. Todos los sistemas preparados, monómeros y homopolímeros fueron caracterizados por las técnicas espectroscópicas de RMN 1H y 13C, FTIR y por Calorimetría Diferencial de Barrido( DSC). This article describes the preparation of new acrylic stimuli sensitive (pH ) polymers derived from morpholine and pyrrolidine using water as a solvent. Three new methacrylic monomers, N-ethyl morpholine methacrylate (EMM), N-ethyl morpholine methacrylamide (EMA) and N-ethyl pyrrolidine methacrylamide (EPA) have been synthesized. The corresponding monomers EMM,EMA and EPA were homopolymerized at 50 ºC in solutions of water/isopropanol using ammonium persulphate as radical initiator. All the prepared systems, monomers and homopolymers, were characterized by NMR 1H and 13 C, FTIR and DSC spectroscopic techniques.
