An ethylene-(meth)acrylic acid copolymer has a polydispersity index (PDI) in a range from 3.5 to 8.0, and has a melt flow index (MFI) measured at 190° C. and 2.16 kg in a range from 350 g/10 min to 1800 g/10 min A water-dispersive composition includes the ethylene (meth)acrylic acid copolymer, a neutralizing agent and an aqueous medium.

An aqueous dispersion contains a resin component and water, wherein the resin component contains composite particles (D) having the ethylene-unsaturated carboxylic acid copolymer (A) and the polymer having an acrylic acid ester unit as a polymerization unit (B), and composite particles (E) having the ethylene-unsaturated carboxylic acid copolymer (A) and the ethylene-vinyl acetate copolymer (C).

Disclosed is a nonaqueous electrolyte battery using an aqueous sealant composition. The aqueous sealant composition comprises an aqueous dispersion in an amount of 70 mass % or more and 97 mass % or less by mass of solid content, wherein the aqueous dispersion comprises an olefinic polymer as a main component, and a water-soluble polymer in an amount of 3 mass % or more and 30 mass % or less by mass of solid content. The aqueous dispersion comprises an olefinic polymer as a main component. The olefinic polymer is a modified olefinic polymer. The modified olefinic polymer is a partial copolymer of a polymer selected from a group consisting of polyethylene, polypropylene, polybutene and ethylene-propylene polymers, and a polymerizable unsaturated organic acid selected from a group consisting of maleic anhydride, acrylic acid, methacrylic acid and esters thereof.

Provided are adhesive articles that include a barrier layer that is substantially impermeable to oxygen gas at ambient temperature and pressure along with a heat-bondable layer, which could be a discrete layer adjacent to the barrier layer or integral with the barrier layer. The adhesive article further includes a backing extending across and coupled to the barrier layer and an adhesive layer extending across and coupled to the backing opposite the barrier layer. The barrier layer reduces or eliminates migration of plasticizers from the bonded seal into the adhesive article, limiting deterioration of tape performance over time.

The present disclosure includes articles formed from substrates with coatings, e.g., articles with heat-sealed coatings, and methods of preparation thereof. At least one of the coatings of the articles herein may serve as a water barrier. The coatings may comprise, for example, polymer(s), or polymer(s) and mineral(s), and may include one layer or multiple layers of such material(s) or combinations of materials. The articles herein may be used as containers, such as paper cups.
