Thermo-responsive polymers and copolymers derivatives of oligo(ethylene glycol) methyl ether methacrylate ( M  n = 300 g mol -1 ) (OEGMA) and di(ethylene glycol) methyl ether methacrylate (DEGMA) have been synthesized by reversible addition fragmentation chain transfer polymerization (RAFT) using 5-amino-4-methyl-4-(propylthiocarbonothioylthio)-5-oxopentanoic acid (APP) as chain transfer agent (CTA). The monomer conversion was evaluated by hydrogen nuclear magnetic resonance ( 1 H-NMR); number average molecular weights ( M  n ), weight average molecular weight ( M  w ), and dispersity ( Đ ) were obtained by gel permeation chromatography (GPC); glass transition temperature ( T  g ) was evaluated by modulated differential scanning calorimetry (DSC), cloud point temperature ( T  cp ) was measured and compared by turbidimetry and dynamic light scattering (DLS). The effect of polymer composition and concentration on the T  cp , either in water or in phosphate buffer saline (PBS), was studied. The values of Tcp using PBS were between 3 and 4 °C lower than using water. Results showed an ideal copolymerization behavior; therefore, the T  cp could be tuned by an adequate monomers feed ratio obtaining polymers which may be used in drug delivery and other applications.
