  • Method for producing a dispersion comprising a two stage reaction product and an associated coating
    Patent number: 8242211
    Abstract: The present invention is directed to a method for producing a dispersion comprising: (a) forming a first reaction product by reacting: (a1) at least one monomer comprising an ethylenically unsaturated double bond; (a2) at least one carboxylic acid group-containing monomer; and (a3) at least one glycidyl ester compound; wherein the molar ratio of (a2) to (a3) is substantially 1:1; (b) forming a second reaction product in the presence of the first reaction product by reacting: (b1) at least one monomer comprising an ethylenically unsaturated double bond; and (b2) at least one carboxylic acid group-containing monomer; and (c) reacting an amine compound with the second reaction product; and wherein steps (a), (b), and (c) are conducted in a substantially solvent free environment.

  • METHOD FOR PRODUCING A DISPERSION COMPRISING A ONE STAGE REACTION PRODUCT AND AN ASSOCIATED COATING
    Publication number: 20100190923
    Abstract: The present invention is directed to a method for producing a dispersion comprising: (a) reacting (i) a monomer comprising an ethylenically unsaturated double bond; (ii) a carboxylic acid group-containing monomer; and (iii) a glycidyl ester compound to form a reaction product comprising a carboxylic acid group; and (b) reacting the reaction product of (a) with an amine compound; and wherein there is a molar excess of (ii) to (iii); wherein steps (a) and (b) are conducted in a substantially solvent free environment and wherein the reaction product of (b) is not further reacted with a polyester polyol.
