Abstract: Disclosed is a composition which comprises or consists essentially of a high melt index ethylene acid copolymer comprising monomer units derived from ethylene, an alkyl (meth)acrylate, a (meth)acrylic acid, and an optional comonomer. Also disclosed is a composition comprising the ethylene acid copolymer crosslinked with a polyamine, a polyvalent metal salt, or combinations thereof. Also disclosed is a solution of the ethylene acid copolymer which can be used for solutions application to substrates.

Abstract: A composition and an article made from the composition are disclosed. The composition comprises, or is produced from, an ionomer, a polyamide, and one or more esters of montanic acid. The article includes film, sheet, filament, tape, molded part, thermoformed product, and container for food or non-food packaging, or combinations of two or more thereof.

Abstract: Ionomeric compositions which are blends of a first ethylene/acid copolymer polymerized at low temperatures and normal pressures, and a highly neutralized second ethylene/acid copolymer, polymerized at normal polymerization temperatures and pressures but having a high melt index, above 80 g/10 min., in the parent acid copolymer and also a high melt index, above 3.0 g/10 min., in the resulting neutralized ionomer, have both improved high temperature mechanical properties and improved melt processability. Alternatively, the first and second acid copolymers may be blended and neutralized in the same melt process step, or first melt blended, and then neutralized in a subsequent melt process step.
