Abstract: This invention relates to a cosmetic film forming composition which is especially useful as a nail coating composition which upon drying forms a film which will adhere to keratin of a nail. More particularly, the present invention relates to cosmetic film forming compositions which consist of aqueous emulsion (A) which comprises a sulfopolyester and a copolymer of vinyl acetate and dialkyl maleate, and aqueous emulsion (B) which comprises an aqueous emulsion of acetoacetoxyethyl alkylacrylate or the reaction product of acetoacetoxyethyl alkylacrylate with a vinylfunctional monomer. These cosmetic film forming compositions are fast drying, have good adhesive properties and are environmentally compatible.

Abstract: Disclosed is a process for isolating copolymers comprising repeating units from 2-vinylpyridine and styrene by drowning the reaction emulsion into an acetic acid solution or by adding an acetic acid/water solution to the reaction emulsion. The copolymer isolated by this technique filters and washes much more rapidly than the copolymer isolated using sodium chloride, and the wet cake has a high solids content.

Abstract: Coating compositions and pellets coated therewith which are adaptable for oral administration to ruminants are disclosed. The coating protects the core material of the pellets in the rumen and releases it postruminally. The coating is a specific mixture of a film-forming polymeric material, hydrophobic material and flake material.
