DOI: 10.1016/j.eurpolymj.2017.08.046
Abstract: Abstract Non-isocyanate thermoplastic polyureas (NIPUreas) were synthesized using an original approach. Dimethyl dicarbamates (DC) were prepared as monomers, by the reaction of a diamine with an excess of dimethylcarbonate (DMC), in presence of 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD)… read more here.
