The ring-opening copolymerization of epoxides with isothiocyanates (ITCs) is explored for the first time. In presence phosphazenium benzoxide, investigated in this work including propylene oxide, ethylene and cyclohexene oxide were successfully copolymerized both an aromatic ITC, phenyl isothiocyanate, two aliphatic ITCs, ethyl isothiocyanate hexyl isothiocyanate. Effects phosphazene bases used...

The solid-state structure–property behavior of highly branched segmented poly(urethane urea) (PUU) copolymers and their linear analog was investigated. A limited study of their solution rheological behavior was also undertaken. The linear PUUs were synthesized by the twostep prepolymer method, whereas the oligomeric A2CB3 methodology was utilized to synthesize the highly branched materials. The...

Abstract In this work, new bio-based copoly(ester amide)s were synthesized by a two-step melt polycondensation process, using 2,5-furanedicarboxylic acid dimethyl ester (DMFDC), 1,3-propanediol (PDO), and 1,3-diaminopropane (DAP), with different DAP content. The chemical structure of the obtained poly(trimethylene 2,5-furandicarboxylate)-co-poly(propylene furanamide) (PTF-co-PPAF) copolymers wa...

Brush-type macromolecules (BMs) have attracted much attention over the past decades because of their unique properties and potential applications in nanoscience, drug-delivery systems, photonics. A two-step strategy synthesis polycarbonate-grafted copolymers with either star-shaped or brush-typed morphologies using a “grafting from” approach is reported; backbone these all-polycarbonate graft m...
