Novel fully renewable AA-BB type nonisocyanate polyurethanes (NIPUs) were synthesized using the transurethanization approach. Dicarbamate monomers were prepared 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) as catalyst. Then, the dicarbamate was reacted with a diol to afford the polymer, in presence of TBD or K 2 CO 3 as catalyst. Several renewable diamines and diols were tested. The two steps were conducted under neat conditions. The obtained Polym. Chem. 2015, 00, 000-000

Novel fully renewable AA-BB type non-isocyanate polyhydroxyurethanes were synthesized by the classical reaction between a diamine and a dicyclocarbonate. Sebacic acid was first reacted with an excess of glycerol carbonate, in presence of DCC and DMPA, leading to a renewable dicyclocarbonate monomer. Then, this monomer was reacted with several renewable diamines, in presence of 1,5,7-triazabicyclo

An antiadhesive nanofilm has been designed and prepared in one step in water onto commercial poly(dimethylsiloxane) (PDMS) by mimicking the external region of cell membranes. The resulting biomimetic surfaces are effective in suppressing protein adsorption as well as bacterial and mammalian cell adhesion.
