- W2187351628 abstract "diamino phenyl phenylcarbamate- an AB2- type blocked isocyanate monomer was synthesized. Step- growth polymerization of this monomer was found to give a hyperbranched poly (aryl-urea). The polymers were characterized by FT-IR, 1 H-NMR, TGA and DSC measurements. Molecular weights (Mw) of the polymers were determined using GPC. The polydispersity indexes were relatively narrow due to the controlled regeneration of isocyanate functional groups for the polymerization reaction. The polymers were found to be soluble in DMF, DMSO, NMP, DMAc, and THF. All the polymers underwent two-stage decomposition and were stable up to 220 o C. Functionalized end-capping of poly(aryl-urea) using phenylchloroformate changed the thermal properties and solubility of the polymers. Copolymerization of AB2- type blocked isocyante monomer with functionally similar AB monomer was also carried out. The molecular weights of copolymers were found to be higher than homopolymers with narrow dispersity. It was found that the Tg's of poly(aryl-urea)s were significantly less compared to copoly(aryl-urea)." @default.
