Disclosed is a modified biopolymer having the formula A-XY wherein: (a) A is a starting material selected from the group consisting of a polysaccharide, a protein and a cellulose; (b) X is a first moiety bearing a functionality co-reactive with A; (c) Y is a second moiety covalently bound to X, capable of undergoing free radical polymerization and bearing at least two ethylenically unsaturated functional groups; (d) the starting material A and the first moiety X are linked covalently through linkages selected from the group consisting of an ester, an amide, a urethane, a urea, a sulfonate ester, a phosphate ester and an ether; and (e) a degree of substitution of the starting material A with the first moiety X is less than 0.5 but more than 0.1. Compositions including the modified biopolymer and methods for making them are also disclosed.

Environmentally biodegradable microcapsules

A method and kit for treating a nail surface. The method includes brushing or spraying an adhesive on a coated or uncoated nail surface to form an adhesive-coated surface. A covering (e.g., a curable nail gel, evaporative nail polish, or artificial nail) is then applied to the adhesive-coated surface. The covering is removable by soaking in solvent for less than 20 minutes, peeling, or a combination thereof.

Methods and compositions for readily removing nail coatings

A top coat nail polish formulation comprising a primary film-forming polymer, a secondary film-forming polymer, a plasticizer and a solvent yields a haze free film upon drying. The secondary film-forming polymer is prepared by a reaction methacrylic acid, alkylacrylate, and of methyl methacrylate, at selected ratios. The alkylacrylate comprises a branched alkyl group with 4 to 12 carbons, or a mixture of branched alkyl groups and optionally linear alkyl group. The haze of the dried top coat film depends on the presence of methacrylic acid, ratio of alkylacrylate to methyl methacrylate, the number of carbons in the alkyl group on the alkylacrylate, and the branching of the alkyl group.

Low haze film formers for top coat nail polish

The present invention provides aqueous binder compositions comprising one or more polyol and a multistage copolymer, preferably, an all acrylic and allylic or all acrylic copolymer, having as the outermost stage a polymerized acid functional aqueous solution polymer and as the one or more remaining stage(s) a vinyl emulsion polymer, wherein the emulsion polymer stage(s) in the multistage copolymer comprises 5 wt. % or less of hydrophilic monomer, based on the total weight of monomers used to make the emulsion polymer stage(s). The multistage copolymer enables incorporation of a much higher amount of hydrophilic monomer into a polymeric binder without the attendant handling or viscosity problems. Also provided are methods of using the aqueous binder compositions comprising pultruding two or more non-woven fibers or a fiber roving with the aqueous binder composition, and drying, Articles comprising the bound fiber(s) are provided.

Curable formaldehyde free compositions as binders having solvent resistance

The present invention provides aqueous multistage copolymers, preferably, all acrylic and allylic or all acrylic copolymers, having as the outermost stage an acid functional, preferably, carboxyl or carboxylate functional, aqueous solution polymer and as the one or more remaining stage(s) a vinyl emulsion polymer, wherein the vinyl emulsion polymer stage(s) in the multistage copolymer comprises 5 wt. % or less of hydrophilic monomer, based on the total weight of monomers used to make the vinyl emulsion polymer stage(s). The multistage copolymer enables incorporation of a much higher amount of hydrophilic monomer into a vinyl emulsion copolymer. In addition, are methods of methods of making the multistage copolymers are provided.

Aqueous polymer grafted latex

The present invention provides aqueous coating compositions comprising one or more emulsion copolymer made from itaconic acid, a sulfonic acid or sulfonate ester monomer and an additional acid monomer which is a carboxylic acid and having a glass transition temperature of from &#x2212;45&#xb0; C. to &#x2212;10&#xb0; C., and one or more pigment, opacifier, filler, extender, or mixture of any of these at a % PVC of from 20 to 55, preferably 30 to 50, wherein coatings made from the coating compositions provide improved resistance to water swelling and dirt pickup resistance. The improvements are observed regardless of whether the compositions contain or are substantially free of zinc or divalent metal ions, or salts or compounds containing them. The present invention also provides roofing substrates coated with the aqueous compositions.
