ABSTRACT Novel fully renewable AA‐BB type nonisocyanate polyurethanes (NIPUs) were synthesized using the transurethanization approach. Dicarbamate monomers prepared by reaction of a diamine with an excess dimethylcarbonate (DMC), in presence 1,5,7‐triazabicyclo[4.4.0]dec‐5‐ene (TBD) as catalyst. Then, dicarbamate was reacted diol to afford polymer, TBD or K 2 CO 3 Several diamines and diols tested. The two steps conducted under neat conditions. obtained materials exhibited T g values varying...
ABSTRACT Novel fully renewable AA‐BB type non‐isocyanate polyhydroxyurethanes were synthesized by the classical reaction between a diamine and dicyclocarbonate. Sebacic acid was first reacted with an excess of glycerol carbonate, in presence DCC DMPA, leading to dicyclocarbonate monomer. Then, this monomer several diamines, 1,5,7‐triazabicyclo[4.4.0]dec‐5‐ene (TBD), as organocatalyst, afford linear branched polymers. The obtained materials exhibited T g values varied from −27 −8 °C, m...
ABSTRACT Nonisocyanate thermoplastic polyurethane elastomers (NIPUs) were synthesized with the transurethanization approach. Dimethyl dicarbamates (DCs) prepared by reaction of a diamine an excess dimethyl carbonate in presence 1,5,7‐triazabicyclo[4.4.0]dec‐5‐ene (TBD) as catalyst. Then, polymers obtained under neat conditions through DC polyethyleneglycol average molecular weight 1500 g/mol (PEG1500) at variable temperatures different amounts 1,4‐butanediol. TBD, dibutyltin dilaurate...
A heterogeneous catalyst for producing epoxidized vegetable oils, an important intermediate in the production of non-isocyanate polyurethanes, is essential product separation and decreasing side-reaction, i.e., ring-opening reaction, via Prileschajew method. The development reliable kinetic models considering key variables both phases mass transfer phenomena missing literature. reaction pathway also under debate. Therefore, we studied kinetics epoxidation cottonseed oil by perpropionic acid...
An antiadhesive nanofilm has been designed and prepared in one step water onto commercial poly(dimethylsiloxane) (PDMS) by mimicking the external region of cell membranes. The resulting biomimetic surfaces are effective suppressing protein adsorption as well bacterial mammalian adhesion.
Abstract New hydroxytelechelic cis ‐1,4‐oligoisoprenes exhibiting variable values and distributions of the hydroxyl functionality were successfully prepared. The synthesis reactions involved chemical modifications carbonyl telechelic ‐1,4‐polyisoprene, which was obtained by controlled degradation synthetic or natural rubber. These new oligomers reacted with toluene diisocyanate to elaborate crosslinked polyurethane elastomers. thermomechanical properties prepared polyurethanes investigated....
