In this poster presentation, we will discuss a new synthesis of thermoresponsive polymers. In this synthesis, commercially available and inexpensive primary amines and di-epoxide molecules are utilized as AA- and BB-types of monomers in an amine-epoxy ‘click’ polymerization process. This process does not require a catalyst or inert conditions. A simple monomer mixing and stirring approach affords poly(ß-hydroxyl amine)s in a scalable manner. The prepared polymers show lower critical solution temperature (LCST) that can be tuned through adjusting the molecular structure of the amine or the epoxy monomer. For example, amine monomers carrying a hydrophilic side-chain exhibits higher LCST than monomers carrying a hydrophobic side-chain. Similarly, hydrophilic epoxy monomers give rise to polymers exhibiting a higher cloud point than their hydrophobic counterparts. |
