ABSTRACT External catalysts were used to promote dynamic exchange reactions within polyhydroxyurethanes (PHUs) derived from 6‐membered cyclic carbonates (6CCs). Owing to the presence of both carbamate and ester linkages in the network, two types of covalent exchange reactions; transcarbamoylation and transesterification can …

(Meth)Acrylic end-capped non-isocyanate polyurethanes (NIPUAs) were synthesized via transurethanization. The resulting prepolymers were then blended with acrylic monomers to produce UV-curable hybrid urethane/acrylic coatings. The structural characterization of the prepolymers before curing was performed using Fourier transform infrared spectroscopy (FTIR), proton nuclear …
