Abstract

A hot alkaline liquid soluble or dispersable composition made from a first polymer of an ethylene-acrylic acid copolymer having an acrylic acid portion, an ethylene-methacrylic acid copolymer having a methacrylic acid portion, or a mixture thereof, where the acrylic acid portion and the methacrylic acid portion each, independently, comprise from 10 to 30 wt. % of the total copolymer weight and also including an Ionomer-type copolymer having an acrylic acid portion, a methacrylic acid portion, or a combination thereof, comprising from 10 to 30 wt. % of the total Ionomer copolymer weight. Methods of making articles from such compositions. Methods of disposal of such compositions in hot liquid and alkaline conditions. A method of disposing of a hot alkaline liquid soluble or dispersable product by contacting the product with a hot alkaline liquid for a period of time sufficient to dissolve or disperse the product, the product comprised of either a first polymer of an ethylene-acrylic acid copolymer having an acrylic acid portion, an ethylene-methacrylic acid copolymer having a methacrylic acid portion, or a mixture thereof, wherein the acrylic acid portion and the methacrylic acid portion each, independently, comprise from 10 to 30 wt. % of the total copolymer weight, an Ionomer copolymer having an acrylic acid portion, a methacrylic acid portion, or a combination thereof, comprising from 10 to 30 wt. % of the total Ionomer copolymer weight, or a mixture thereof.
