Abstract: Novel latex or emulsion compositions containing internally plasticizing and crosslinkable monomers derived from traditional semi-drying or non-drying oils are disclosed and claimed. The monomers are ethylenically unsaturated derivatives of long-chain olefinic compounds. Preferred embodiments include latex formed from acrylate or methacrylate esters of fatty alcohols. A process for the synthesis of the latex composition is also disclosed, which involves (a) polymerization of the ethylenically unsaturated derivatives of a long-chain olefinic compound in an aqueous phase with at least one other copolymerizable monomer; and (b) blending of so formed polymer with at least one drier and a surfactant to form the novel latex or emulsion compositions. These compositions form films at low minimum film forming temperatures (MFT) ranging from −5 to 10° C.

Abstract: A process is disclosed for the preparation of imidazole derivatives, in particular, 1-aryl-2-(1-imidazolyl) alkyl ethers and thioethers, and more particular for the preparation of tioconazole. The preferred process involves alpha bromination of thiophene in cyclohexane, coupling with an imidazole to form the crude product, and forming the bisulfate salt thereof. The reaction utilizes less hazardous chemicals than currently employed for the production of 1-aryl-2-(1-imidazolyl) alkyl ethers and thioethers, and may be run at room temperature.

Abstract: A method is provided for purifying a crude N-acetyl-para-aminophenol (APAP) containing color bodies or their precursors, the method comprising: a) forming a hot aqueous solution of the crude APAP; and b) subsequently contacting the hot solution with an acid washed adsorbent carbon, e.g., an activated carbon, which acid washed carbon, prior to such contact, has been pretreated by contacting it with an aqueous solution of a reducing sulfite.

Abstract: Novel powder coating compositions containing reactive hyperbranched polymers are disclosed and claimed. Preferred embodiments include powder coating compositions formed from hyperbranched polyesters having terminal hydroxy, carboxy, epoxy, and isocyanate groups. Preferred hyperbranched polyesters are formed from .alpha.,.alpha.-bis-(hydroxymethyl)-propionic acid, which act either as crosslinkers, adhesion promotors, or flow and leveling agents.

Abstract: Novel latex or emulsion compositions containing internally plasticizing and crosslinkable long-chain alkenol ester monomers are disclosed and claimed. Preferred embodiments include latex formed from acrylate or methacrylate esters of long-chain alkenols. A process for the synthesis of the latex composition is also disclosed, which involves (a) esterification of a long-chain alkenol with an ethylenically unsaturated carboxylic acid; (b) polymerization of the ethylenically unsaturated ester in an aqueous phase with at least one other copolymerizable monomer; and (b) blending of so formed polymer with at least one drier and a surfactant to form the novel latex or emulsion compositions. These compositions form films at low minimum film forming temperatures (MFT) ranging from -5 to 10.degree. C. and cure to above ambient glass transition (T.sub.g) polymers without the use of traditional organic cosolvents which contribute to environmental pollution via volatile organic compounds (VOCs) emissions.
