摘要

实现二氧化碳（CO

）与环氧丙烷（PO）共聚反应制备聚(醚-碳酸酯)多元醇无论对CO

的资源化利用还是高性能聚氨酯材料的开发都具有重要意义。然而，CO

与PO共聚反应研究主要聚焦于催化剂的开发，而忽略了共聚反应的动力学研究，无法为其生产工艺提供指导。对此，本文利用原位红外光谱仪研究聚合反应历程，考察了双金属Co-Zn氰化物催化的CO

与PO共聚的反应动力学。共聚过程中，PO呈一级反应动力学，且反应活化能为37.35 kJ/mol。基于此，建立了共聚反应的动力学方程。在此基础上，制备了不同醚单元含量的CO

-polyol，有效调控CO

的玻璃化转变温度，为CO

与PO共聚反应工业化生产制备CO

-polyol提供了基础。

Abstract

The copolymerization of carbon dioxide (CO

) with propylene oxide (PO) to poly(ether-carbonate) polyols is highly significant in terms of both the resource utilization of CO

and the development of high-performance polyurethane materials. However

research on the CO

/PO copolymerization has primarily focused on developing effective catalyst; whereas

studies involving the kinetic aspects of this copolymerization are concerned

which fails to provide guidance for its production processes. Herein

we made effort to disclose the kinetical parameters of this copolymerization by in

vestigating the polymerization process using in-situ infrared (IR) spectroscopy. For the bimetallic Co-Zn cyanide complex-catalyzed CO

/PO copolymerization

the reaction order for PO were determined to be first-order

together with reaction activation energy of 37.35 kJ/mol. On the basis of these results

-polyols with varying polyether segment contents were prepared

which allows the adjustment of the glass transition temperatures of the CO₂-polyols

providing a foundation for the industrial production of CO

-polyol via the CO

/PO copolymerization.
