    摘要: Disclosed are methods to form coatings on a substrate, the coatings comprising a blend of a poly(vinyl alcohol) composition comprising a poly(vinyl alcohol) characterized by a hydrolysis level of from about 85 to about 93 mole % and a 4 weight % aqueous viscosity at 20° C. of about 16 to about 75 centipoise; and an ionomer comprising a parent acid copolymer that comprises ethylene and about 18 to about 30 weight % of acrylic acid or methacrylic acid, the acid copolymer having a melt flow rate from about 200 to about 1000 g/10 min., wherein about 50% to about 70% of the carboxylic acid groups of the copolymer are neutralized to carboxylic acid salts comprising potassium cations, sodium cations or combinations thereof. Multilayer structures comprising the blend composition on a substrate are also disclosed.
