Abstract: A falling film apparatus has tube inserts located at the top end of heat exchange tubes. The tube inserts have internal circumferential ribs. The ribs distribute a process flow into a uniform, annual film within the tube inserts and the tubes, and eliminate dry spots, even at low operating rates. This provides greater operating latitude, can improve operating efficiency and can reduce fouling.

Abstract: The present invention relates to a method for preparing an aqueous dispersion of acrylate-siloxane copolymer particles as described herein. The polymer particles comprise 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 method provides an efficient way to prepare a high solids content aqueous dispersion of siloxane-acrylate hybrid copolymers with efficient incorporation of siloxane acrylate monomers, low residual monomer, and low generation of unwanted coagulum. The dispersion is useful for forming coatings with improved hydrophobicity, stain resistance, and aesthetic/haptic properties compared with conventional all-acrylic compositions.
