  • Publication number: 20120329972
    Abstract: Resins derived significantly from renewable or recyclable starting materials may be formed from the reaction product of a monomer blend that includes an ethylenically unsaturated macromonomer and at least one other ethylenically unsaturated monomer, which may be acid functional. The ethylenically unsaturated macromonomer may be derived from the reaction of an acid functional intermediate, which may be the acidolysis reaction product of an engineered polyester and an acid or anhydride functional material with an hydroxyl-functional, amine-functional, or epoxy functional reactant, optionally in the presence of a polyacid, to yield a resin intermediate, which may subsequently be reacted with an ethylenically unsaturated coupling agent to yield the macromonomer. The resins described herein are useful in generating low VOC acrylic alkyd coatings. Methods of producing water reducible resins are also described.

  • Patent number: 7129278
    Abstract: The overall performance of water-reducible polymer dispersions, more specifically alkyd dispersions, can be substantially improved by utilizing resins derived from acidolysis reaction products of polyalkylene terephthalates and polyalkylene naphthalates.
