SYNTHETIC METHOD FOR THE PREPARATION OF RHEOLOGICAL MODIFYING POLYMERS AND THE USE THEREOF

The invention relates to a UV-initiated RAFT-type polymerization for producing hydrophobically associative terpolymers in an aqueous solution. The terpolymers produced by this method can be used as aqueous rheological modifiers. Specifically, the invention relates to a hydrophobically associating terpolymers and a method to produce same using a light initiated iniferter. The monomers used in the present invention are selected from: a monomer having a water-soluble monoethylenically unsaturated group; a monomer having an ionic water-soluble monoethylenically unsaturated group; and a monomer having a monoethylenically unsaturated monomer capable of forming hydrophobically associative bonds in aqueous medium. The iniferter is initiated with light of wavelength between 250-400 nm. The resultant terpolymer is produced in a cost-effective, simple, and one-step process and can be used to thicken aqueous mediums with less or equal amounts of polymer than currently available.
