Title:

HYDROPHILIC-HYDROPHOBIC THERMALLY REVERSIBLE MATERIAL

Document Type and Number:

Japanese Patent JPS62277414

Kind Code:

A

Abstract:

PURPOSE: To provide the titled material composed of an aqueous solution of a poly[N-(dimethoxyethyl)-N-methylacrylamide], reversibly taking a water-soluble state at low temperature and water-insoluble state at high temperature and useful as a light-shielding material, temperature sensor, heat-sensitive switch, toy, adsorptive separation material, etc.

CONSTITUTION: The objective material is composed essentially of an aqueous solution of poly(N-(2,2-dimethoxyethyl)-N-methylacrylamide)(preferably having an intrinsic viscosity [η] of 0.01W6.0 in methanol solution at 30°C). The concentration of the aqueous solution is preferably ≥0.01%.
