Abstract

A polymer produced by polymerizing via water-in-oil emulsion polymerization one or more water soluble monomers with one or more polyalkoxylated monomers wherein said one or more polyalkoxylated monomers contains at least 25 alkylene oxide units and wherein said product demonstrates thermothickening properties, its method of manufacture and use thereof is disclosed.

Claims (2)

1. A method for producing a polymer which demonstrates thermothickening properties by polymerizing via water-in-oil emulsion polymerization one or more water soluble monomers with one or more polyalkoxylated monomers wherein said one or more polyalkoxylated monomers contains at least 25 alkylene oxide units.

2. The method of claim 1 wherein a thermothickening enhancing effective amount of a nonionic surfactant is added to the polymer.
