Abstract: Alkali-swellable rheology modifier comprising a core-shell polymer comprising a core polymer and a shell comprising at least one shell copolymer layer at least partially cross-linked and containing a mole percent of crosslinking agent greater than the mole percent of crosslinking agent in the core polymer, provided if the mole percent of crosslinking agent in the core polymer is zero, then either the core polymer is greater than 60 wt % of the core-shell polymer; the core polymer comprises at least one associative monomer; at least one shell copolymer layer copolymer comprises at least one associative monomer; and/or the at least one shell copolymer layer that is at least partially cross-linked comprises greater than 3 mole % crosslinking agent. Aqueous compositions comprising the alkali-swellable rheology modifier include personal care formulations, healthcare formulations, agricultural formulations, paint formulations, coating formulations, laundry and fabric care formulations, household cleaning formulations, and industrial and institutional cleaning formulations.

Abstract: A method of making a pyranine monomer composition comprises the step of reacting pyranine with a functionalizing agent that functionalizes the pyranine molecule with a polymerizable functional group to provide a composition of functionalized pyranine monomers, said functionalization reaction taking place in an aqueous reaction medium, and in the presence of a molar excess of said functionalizing agent, such that the functionalization reaction product is a monomer composition substantially free of unfunctionalized pyranine compound. The pyranine monomer compositions made by the method can be used to make fluorescent tagged water soluble polymer compositions that advantageously are substantially free of unpolymerized pyranine. The fluorescent tagged water soluble polymer compositions can be used in a method of inhibiting scale in industrial water systems.
