Direct Synthesis of Polyurea Thermoplastics from CO and Diamines.

The transformation of CO into polymeric materials is an important and hot research topic from the viewpoint of renewable resources and environmental effects. Herein, a series of polyureas have been synthesized by polycondensation from CO with diamines of 1,12-diaminododecane (DAD) and/or 4,7,10-trioxa-1,13-tridecanediamine (TTD). The properties of polyureas synthesized were characterized by FTIR, H NMR, C NMR, XRD, DSC, TGA, and DMA.
