Abstract

A thermoreversible thickener comprising a water-soluble copolymer containing as constituent monomer more than 50% by weight of a vinyl carboxylic ester of a cylic amine or a non-cyclic amine with more than 5 carbons with an alkylene oxide added thereto. The thickener, with a transition temperature which can be easily controlled according to the purpose of application, has a characteristic such that heating the aqueous solution thereof up to a temperature above the transition temperature causes rapid thickening of the solution.

The composition of the thickener, prepared by admixing from 0.01 to 30% by weight thereof with from 70 to 99.99% by weight of aqueous solutions, emulsions or aqueous dispersions of inorganic or organic substances, can be used for purposes such as coating material compositions, rolling oil compositions, adhesive bonding agents, printing inks, coating materials for coated paper and adhesives for carpet backing.
