Title:
METHOD FOR PREPARING CARBON DIOXIDE-BASED QUATERNARY COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2023/045887
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of IPC C08G64/16, and specifically relates to a method for preparing a carbon dioxide-based quaternary copolymer. The method for preparing a carbon dioxide-based quaternary copolymer comprises the following steps: 1) adding preparation raw materials to a high-pressure reactor, then adding a catalyst, and heating same for a quaternary ring-opening copolymerization reaction; and 2) after the reaction is finished, carrying out a post-treatment to obtain the carbon dioxide-based quaternary copolymer. According to the carbon dioxide-based quaternary copolymer provided in the present invention, by means of adding ethylene oxide and the catalysts of triethylborane or tributylborane and tetra-n-butylammonium fluoride, tetra-n-butylammonium chloride, tetra-n-butylammonium bromide, tetra-n-butylammonium iodide, tetra-n-propylammonium fluoride, tetra-n-propylammonium chloride, tetra-n-propylammonium bromide or tetra-n-propylammonium iodide, the reaction activity can be changed, the time for preparing the high-molecular-weight polymer can be shortened, the energy consumption can be reduced, and the carbon dioxide-based quaternary copolymer has a relatively high reference value when applied to large-scale industrial production.
