Abstract in another language

A well-studied example of a thermoresponsive polymer is PNiPAAm, which exhibits a sharp coil-to-globule transition in water at its LCST. A study relating to the missing counterpart of LCST polymers is presented: N-acryloylglycinamide (NAGA) homopolymer and copolymers from NAGA and N-acetylacrylamide (NAcAAm) that show a sharp UCST (where the sharpness depends on the composition). The polymers were synthesized by free-radical copolymerization and the copolymerization parameters were determined by the method of Kelen-Tüdös. The UCST was investigated by turbidimetry, regarding the influence of the copolymer composition, the polymer concentration and the addition of electrolytes.
