    摘要： A non-gelled copolymer is prepared from: I) at least one ethylenically unsaturated aliphatic or aromatic monomer that is unsubstituted with reactive functionality and/or has hydroxyl functionality, II) an ethylenically unsaturated monomer having one acid functional group; and III) an ethylenically unsaturated oligomeric monomer having a number average molecular weight of about 1500 to about 4000 and which is derived from a hydroxyl functional acid having a predominantly hydrocarbon chain of from about 10 to 19 carbon atoms. The amounts of the monomers based upon the total solid weight of reactants used to prepare the copolymer are: about 80 to about 95 for I; about 3 to about 6 percent for II; and about 2 to about 14 percent for III. The ungelled copolymer can be present with hydrophobic amorphous fumed silica in amounts of about 50 to about 90 for the copolymer and about 10 to about 50 all as percentages by weight based on the weight of the two components. The ungelled copolymer alone or with the silica can be present along with coating components like film forming polymers, aqueous and/or organic solvent vehicles and optionally one or more pigments. In the colored and/or clear coating compositions and in the methods of their application to substrates, the amount of the silica is up to about 2.5 percent by weight, and the ratio of the copolymer to the silica is generally in the range of from about 9:1 to 1:1 to yield coatings with good rheology control.

    摘要： Improved application latitude, including blister resistance, has been found attainable using a coating formulation that includes a water dispersible resin comprising the addition copolymerization reaction product of vinyl monomers including an acid group containing monomer, an N-(alkoxymethyl)acrylamide or N-(alkoxymethyl)methacrylamide monomer, and at least one other vinyl monomer, the reaction being carried out in the presence of a solvent including a polyol, wherein the OH groups of polyol molecule are of unequal reactivity. The copolymer may be blended with an amine modified epoxy resin to form a coating composition particularly suitable for application onto metal surfaces such as can stock.

    摘要： The present invention is directed to a copolymer that includes a first radically polymerizable low surface tension (meth)acrylate monomer and one or more other radically polymerizable ethylenically unsaturated monomers. The copolymer has a polydispersity index of less than 2.5. The present invention further includes a controlled radical polymerization method to make the above described low surface tension containing copolymers. The method includes the steps of adding a first radically polymerizable low surface tension (meth)acrylate monomer and one or more other radically polymerizable ethylenically unsaturated monomers to a solution containing a suitable atom transfer radical polymerization (ATRP) initiator.

    摘要： A method of making a copolymer composition containing a copolymer, which includes the steps of (a) providing a donor monomer composition that includes an isobutylene type monomer; (b) mixing the donor monomer composition with an ethylenically unsaturated monomer composition that includes one or more ethylenically unsaturated acceptor monomers, and is substantially free of maleate type monomers and fumarate type monomers, and (c) polymerizing the mixture resulting from step (b) in the presence of a free radical polymerization initiator. The polymerization is carried out in the substantial absence of Lewis acids and/or transition metals. The isobutylene type monomer is present at a molar excess of at least 10 mol % based on the molar concentration of monomers in the ethylenically unsaturated monomer composition. The ethylenically unsaturated acceptor monomers are present in an amount of at least 15 mol % of the total monomer composition.
