  • Publication number: 20230151549
    Abstract: The present invention relates to an article and a method for its preparation; the article comprises a cured polymeric film superposing paper or paperboard. The polymeric film is derived from a dispersion which comprises: a) a dispersant which is a copolymer with an acid value of 130 or less, comprising structural units of ethylene and a carboxylic acid monomer, wherein the copolymer has a melt flow index in the range of from 50 to 2000 g/10 min at 190° C./2.16 kg; wherein the weight-to-weight ratio of structural units of ethylene to carboxylic acid monomer is in the range of from 95:5 to 70:30; and wherein the dispersant has a concentration in the range of from 9 to 50 weight percent based on the weight of polymer solids in the dispersion; b) a base polymer comprising non-functionalized ethylene-co-alkene copolymers, wherein the weight-to-weight ratio of the structural units of ethylene to alkene is in the range of from 99.8:0.

  • Patent number: 11447600
    Abstract: The present invention provides aqueous compositions for making damage tolerant coatings comprising a blend of (i) from 2 to 30 wt. %, based on the total weight of solids in the composition, of an acid or anhydride functionalized polyolefin dispersion having an average particle size of from 0.2 to 5 microns, and (ii) a film forming dispersion of one or more epoxy resins chosen from epoxy resins having an epoxy equivalent weight (EEW) of from 150 to 4,000 having an average particle size of from 0.2 to 1.0 microns, wherein the polyolefin dispersion is stabilized with from 2 to 8 wt. %, based on the total weight of solids in the composition, one or more anionic surfactants, such as a sulfate containing surfactant, and, further wherein, the compositions have a pH of from 3 to 8.
