ABSTRACT:
An aqueous polymerization method is disclosed for forming polymers containing, as polymerized units, at least one monomer having low water solubility, including the steps of:
(1) complexing at least one monomer having low water solubility with a macromolecular organic compound having a hydrophobic cavity; and
(2) polymerizing in an aqueous system from about 0.1% to about 100%, by weight of the monomer component, based on the total weight of the polymer, of the complexed monomer having low water solubility with from about 0% to about 99.9% by weight, based on the total weight of the polymer, of at least one monomer having high water solubility.
The method is also useful for forming aqueous solution polymers having low water solubility. The method is useful for polymerizing, in an aqueous system, aqueous solution polymers or emulsion polymers, particularly random copolymers, of monomer having a low water solubility which heretofore could not be made satisfactorily without the addition of an organic solvent, comonomer or a high level of surfactant to aid in solubilizing the monomer having low water solubility. The method is also useful for improving the efficiency of chain transfer agents having low water solubility used in aqueous solution and emulsion polymerizations.
