dc.description.abstract | Temperature responsive polymers able to alter their chemical or physical properties have been extensively
investigated. Most of these polymers have an alkane polymer backbone with only carbon-carbon
bonds. In this sense, the design of thermoresponsive polymers not only with sharp transition temperatures
but also possessing hydrolizable linkages such as esters, carbonates or urethanes in the main
backbone are highly desired. Here we show a library of thermoresponsive cationic and anionic polyurethanes
synthesized by copolymerization of isophorone diisocyanate with poly(ethylene glycol) and
ionic diols. These polyurethanes exhibit lower critical solution temperatures (LCST) that can be easily
tuned from 20 C to 60 C by altering the polyurethane composition. Our findings show that LCST
temperature could be reduced by the using poly(ethylene glycol) of lower molecular weight and/or
increasing the hydrophobicity of the employed ionic diol. We also demonstrated that the thermoresponsive
behavior could be translated to hydrogels based on those ionic polyurethanes. These “a la carte”
thermoresponsive polyurethanes materials present a great potential in the biomedical field due to the
presence of hydrolizable linkages in the main polymer backbone | es_ES |
