Title:
FREE RADICAL SOLUTION POLYMERIZATION METHOD, POLYMER, AND USE
Document Type and Number:
WIPO Patent Application WO/2023/222004
Kind Code:
A1
Abstract:
The present invention provides a free radical solution polymerization method, a polymer, and a use. The polymerization method comprises: introducing micro-nano bubbles of gas B into an alkenyl monomer aqueous solution, and initiating free radical solution polymerization of an alkenyl monomer by means of free radicals generated after cavitation of the micro-nano bubbles so as to prepare a polymer. The micro-nano bubbles can generate free radicals by means of cavitation without the need of external stimulation, and in the present invention, the free radical solution polymerization of the alkenyl monomer is initiated by means of the cavitation of the micro-nano bubbles.
