  • Publication number: 20050154163
    Abstract: A carbamate or terminal urea functional vinyl polymer is prepared by reacting a compound having an hydroxyl group and a carbamate group, terminal urea group, or a group that can be converted to a carbamate or terminal urea group, with a cyclic carboxylic acid anhydride group to form an ester bond and a free acid group from the anhydride; and reacting the free acid group with a compound having an epoxide group. The cyclic carboxylic acid anhydride group may be pendant to a vinyl polymer, or one of the compound having an hydroxyl group, a compound having the cyclic carboxylic acid anhydride group, and the compound having an epoxide group may have polymerizable ethylenic unsaturation that is polymerized, optionally with one or more copolymerizable monomers to form a vinyl polymer. When the compound having an hydroxyl group has a group that can be converted to a carbamate or terminal urea group, the group is converted to the carbamate or terminal urea group after step (a).

  • Publication number: 20050079362
    Abstract: Disclosed is a method for making nongelled functional addition polymers from linear unsaturated anhydrides. The method subjects a linear unsaturated anhydride compound, an active hydrogen compound, and an epoxide compound to reaction conditions such that each of the following three reactions occur: (i) polymerization of polymerizable C?C bonds, (ii) ring opening of an anhydride functional group of the linear unsaturated anhydride compound by the active hydrogen compound to create an acid functional group, and (iii) reaction of the acid functional group resulting from the anhydride ring opening with the epoxide compound. At the time of reaction (iii), the acid functional group resulting from the anhydride ring opening may be selected from an ethylenically unsaturated monomer, a polymer, or both. In one embodiment, the method does not include the physical removal of any acid functional monomers or polymerization products. Also disclosed are a curable coating composition and a coated substrate.
