Title:
CARBOXYL GROUP-CONTAINING CROSSLINKED POLYMER OR SALT THEREOF, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/215380
Kind Code:
A1
Abstract:
The present invention provides a carboxyl group-containing crosslinked polymer or a salt thereof, which can achieve both coatability and coating film performance of a composition containing the crosslinked polymer or the salt thereof. The carboxyl group-containing crosslinked polymer or the salt thereof is provided such that the non-uniform network structure size Ξ of the crosslinked polymer is at most 80, as calculated by curve fitting, with equation (1), the scattering intensity curve I (q) which is obtained by measuring a 1 mass% aqueous solution of the crosslinked polymer neutralized to a neutralization degree of 50-100 mol% through a small-angle X-ray scattering method (measuring temperature: 25.0±0.1°C). I(q): Intensity of scattered radiation
Ξ: Non-uniform network structure size of crosslinked polymer
A: Fitting parameter
B: Fitting parameter
q: Scattering vector
q*: Distance between charged groups
L: Electrostatic shielding length of polymer chain
m: Fitting parameter
