摘要： The present invention relates to a composition comprising an aqueous dispersion of acrylate-siloxane copolymer particles comprising structural units of an acrylate monomer; an acid monomer; and a siloxane acrylate monomer of formula I: where R, R1, R2, Y and x are as defined herein. The composition has a high solids content, a low concentration of siloxane acrylate monomer and low coagulum levels. The composition is useful for forming coatings with improved hydrophobicity, stain resistance, and aesthetic/haptic properties compared with conventional all-acrylic compositions.

摘要： 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.
