Abstract:

The addition of co-complexing agent is beneficial to improve the catalytic activity of the double metal cyanide(DMC) catalyst. In this paper poly(propylene carbonate tetrachlorophthalic phthalate)(PPCPA) terpolymers were successfully synthesized from carbon dioxide, propylene oxide and tetrachlorophthalic anhydride catalyzed by ball milling synthesized Zn-Co DMC catalysts. The properties and structures of Zn-Co DMC catalysts and the resulting terpolymers were characterized by Fourier transform infrared spectroscopy(FTIR), scanning electron microscope(SEM), X-ray diffraction(XRD), gel permeation chromatography(GPC) and thermogravimetric analysis(TG). The results show that the turnover number of Zn-Co DMC catalysts is up to 25.67~141.80, and the number-average relative molecular mass of PPCPA is up to 2.21×103~3.15×103 with a narrow polydispersity index of 1.04~1.24. Compared with polypropylene carbonate(PPC), PPCPA shows a higher thermal stability, and the thermal decomposition temperature of PPCPA is increased by 129.8 ℃.
