    摘要： Emulsion polymers and coating compositions made therefrom that exhibit exceptional stain resistance to both hydrophilic and hydrophobic stains. The emulsion polymers include, as polymerized units: a) at least one ethylenically unsaturated nonionic monomer in an amount ranging between about 85 wt. % to less than 100 wt. % based on the overall weight of the polymer composition; b) a first acid monomer in an amount ranging from about 0.1 to 2 wt. %, the first monomer being a strong acid monomer selected as a phosphorus-based acid monomer, a sulfur-based acid monomer, or a mixture thereof, and c) a second acid monomer in an amount ranging from about 0.1 to 2 wt. %, the second monomer being one or more ethylenically unsaturated monomers having at least one carboxyl or carboxylic anhydride functional group. The relative amounts of the first and second acid monomers are such that the ratio of b/c is greater than 0.7.

    摘要： Described herein is the synthesis of adhesive from simple adhesive coacervates and their uses thereof. The adhesives are produced by (a) preparing a solution comprising (1) a polyelectrolyte, wherein the polyelectrolyte comprises a polyanion or polycation but not a combination thereof, the polyeletrolyte comprises at least one crosslinking group, and (2) a sufficient amount of a complimentary counterion to produce a simple adhesive coacervate; and (b) crosslinking the simple adhesive coacervate to produce the adhesive. The adhesives have numerous medical and non-medical applications.
