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： A method can selectively prepare a compound of formula (IV), where each R1 and each R2 are independently selected from an alkyl group, an aryl group, a halogenated alkyl group, or a halogenated aryl group of 6 to 10 carbon atoms each R3 is an alkane-diyl group, and each R4 is hydrogen or an alkyl group. The method involves hydrosilylation of an organohydrogensiloxane oligomer with a carboxylic acid alkenyl ester using an iridium complex catalyst.
