  • Epoxy ester copolymer from fatty acid-styrene base
    Patent number: 5124406
    Abstract: The present invention relates to an epoxy ester coating copolymer resin which is useful in the preparation of an air curable, high solids coating, which resin is the reaction product of components (I), (II) and (III); wherein (I) is a polymerizable base of (a) a fatty acid having free radical polymerizable double bonds and (b) a vinyl monomer selected from the group consisting of styrenes, vinyl toluene and mixtures thereof; (II) is an epoxy resin and (III) is a monobasic acid. The epoxy ester copolymer resin of the invention is prepared by the reaction of (I), (II) and (III) at an elevated temperature to an acid number below 10.

  • Water reducible alkyd vinyl copolymer resins
    Patent number: 4720522
    Abstract: A water reducible alkyd vinyl copolymer resin having an acid number in the range of from about 30 to about 70, a method for making the copolymer resin and coating compositions which include the resin are described wherein the copolymer resin is the reaction product offrom about 10 to about 90 percent by weight, based upon the weight of monomers and initiator which provide the alkyd vinyl copolymer resin, of an alkyd resin which is the product of a polymerization reaction and which has an acid number in the range of from about 30 to about 70; andfrom about 10 to about 90 percent by weight based upon the weight of the monomers and initiator which provide the alkyd vinyl copolymer resin, of a vinyl resin which has an acid number in the range of about 30 to about 70.
