球磨双金属氰催化剂催化CO2/环氧丙烷/四氯苯酐三元共聚
Synthesis of Terpolymers Derived from CO2 , Propylene Oxide and Tetrachlorophthalic Anhydride Using Double Metal Cyanide Catalysts by Ball Milling
摘要
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 ℃.关键词
