Nuevos polímeros acrílicos sensibles a estímulos derivados de la morfolina y pirrolidina

Abstract

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.
