Controlling the tacticity in the polymerization of N-isopropylacrylamide: A computational study [PDF]

Polymer, 2011
In this study, the effect of alcohols as solvents on the kinetics and the tacticity of poly(NIsopropylacrylamide) (PNIPAM) is investigated with a combined static and molecular dynamics set of computational tools. Classical molecular dynamics calculations have been carried out to determine the location of the solvent molecules in the proximity of the ...

Self-healing poly(N-isopropylacrylamide) hydrogels

European Polymer Journal, 2015
Abstract Substitution the covalently crosslinked polymer chains by supramolecular ones is a promising strategy to design self-healing hydrogels. Approaches for the synthesis of supramolecular poly(N-isopropylacrylamide) (PNIPAAm) hydrogels with the ability to self-heal are rare because of the bulky side groups of the polymer hindering formation of ...
