Abstract:
The present invention relates to a method for preparing ureido methacrylate comprising the step of contacting, in the presence zinc acetylacetonate (Zn(acac)2) and a radical inhibitor, methyl methacrylate with 1-(2-hydroxyethyl)imidazoline-2-one to form ureido methacrylate. The method provides an efficient and environmentally friendly way of making a key monomer used in the synthesis of acrylic latexes.

Abstract:
Hydroxycarboxylic acids, e.g., 3-hydroxypropionic acid, and/or their ammonium salts are dehydrated to their corresponding unsaturated carboxylic acids, e.g., acrylic acid, by a process that uses a catalyst comprising ammonium bisulfate. The use of ammonium bisulfate reduces or eliminates the problems associated with processes that use sulfuric acid as a dehydrating catalyst, e.g, excess sulfuric acid consumption and/or recovery.
Abstract:
The present invention is a composition comprising a stable aqueous dispersion of polymer particles comprising structural units of a nonionic monoethylenically unsaturated monomer; 2-(methacryloyloxy)ethyl phosphonic acid (MEP) or a salt thereof; and a sulfur acid monomer or carboxylic acid monomer or a combination thereof or a salt thereof, as well as a composite comprising the polymer particles adsorbed to the surface of a pigment particle such as TiO2. The composition and composite are prepared using the phosphorus acid monomer MEP, which can be prepared in high purity with low residual non-polymerizable phosphorus acid, thereby reducing the load of neutralizing agent required to achieve the targeted pH as compared with phophoethyl methacrylate (PEM).
Abstract:
The present invention is a process for converting a phosphonate to a hydroxyalkyl phosphonic acid comprising the step of contacting together water, the phosphonate, and a sulfonated or phosphonated heterogeneous catalyst under conditions sufficient to convert at least 50% of the phosphonate to the hydroxyalkyl phosphonic acid. The process of the present invention provides a way of preparing hydroxyalkyl phosphonic acids safely and economically, without corrosive effects.
