Title:
METHOD OF MAKING BRANCHED POLYMER, BRANCHED POLYMER, AND USES OF SUCH POLYMER
Document Type and Number:
Japanese Patent JP2019196499
Kind Code:
A
Abstract:
To provide polymers containing carbonyl groups conjugated with carbon-carbon double bonds, which allow production of small polymer particles, exhibit no yellow color, and are used as primary suspending agents.SOLUTION: A branched polymer comprises (C=C)-(C=C)-C=O moieties located at chain ends, with a UV absorbance at 280 nm being at least three times the UV absorbance at 320 nm. The polymer comprises residues of: (i) at least one monofunctional monomer having one polymerizable double bond per molecule; (ii) at least one multifunctional monomer having at least two polymerizable double bonds per molecule; and (iii) at least one chain transfer agent comprising an aldehyde or ketone.SELECTED DRAWING: None
