Abstract:
A process comprising:dispersing at least one chemical compound having at least one ethylenically unsaturated group in an aqueous medium and polymerizing the compound with at least one free radical polymerization initiator in the presence of at least one organometallic compound, wherein the organometallic compound has the following structural feature of formula I, â€ƒwhere: Me is a metal ion, â€ƒis a covalent bond or a monoatomic to triatomic covalent, bridging chain, not including the atoms bonded to the chain, and is a covalent bond to a neighboring atom, wherein the organometallic compound has a solubility in acidic, basic, or neutral water at 20Â° C. and 1 bar absolute greater than the solubility in styrene, wherein the polymerizing is a free radical-initiated aqueous emulsion polymerization, and wherein said process provides an aqueous polymer dispersion.
