Document Type and Number:
WIPO Patent Application WO/2021/206042
Kind Code:
A1
Abstract:
Provided is a composition that contains a polymer obtained by polymerizing a water-soluble unsaturated carboxylic acid monomer in the presence of a water-soluble sucrose allyl ether, and that has a low pH and high viscosity. More specifically provided is a composition that has a pH of at most 5.2 and a viscosity of at least 1000mPa·s, and that contains: (A) a polymer obtained by polymerizing a water-soluble unsaturated carboxylic acid monomer in the presence of a water-soluble sucrose allyl ether; (B) a polymer obtained by polymerizing at least acrylic acid and/or methacrylic acid in the presence of pentaerythritol allyl ether, in which the content of pentaerythritol allyl ether is at most 0.1 parts by mass with respect to 100 parts by mass of the acrylic acid and/or methacrylic acid; and water.
