Title:
A COMPOSITION AND ITS APPLICATION IN CONTROLLED LIVING WATER-BASED EMULSION POLYMERIZATION
Document Type and Number:
WIPO Patent Application WO/2023/005567
Kind Code:
A1
Abstract:
The present invention is related to a composition and its application in controlled living water-based emulsion polymerization. The composition comprises at least one organic water-soluble iodine compound, optionally at least one organic-solvent-soluble iodide salt and/or optionally at least one water-soluble iodide salt. When applied in controlled living water-based emulsion polymerization, the resulting polymer shows low PDI and the polymer particle also has a low size PDI.
