POLYMER MATERIAL HAVING PHASE SEPARATION STRUCTURE OBTAINED BY CONTROLLING NUMBER OF BRANCHES

Document Type and Number:

WIPO Patent Application WO/2023/214550

Kind Code:

A1

Abstract:

[Problem] The present invention addresses the problem of providing a novel artificial slime-like polymer material which has stability with respect to an external solvent without changing the chemical compositions of the main chain skeleton, a solvent and the like that constitute the polymer material, and without deteriorating the viscosity and the elasticity of a slime-like substance. [Solution] It is found that a slime-like polymer material in which liquid-liquid phase separation is induced is able to be achieved by controlling the number of branches, the terminal bond ratio, the concentration and the like of a polymer unit that constitutes the polymer material, and that the solubility in an external solvent is consequently able to be controlled.
