    摘要: 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.

    摘要: An article made from a fabric layer permeable to a first liquid such as water, blood or urine. The article has one side that repels the liquid and another side which absorbs the liquid. The article can be disposed of by heating in a selected liquid, which dissolves or disperses the article. The article may also have a plastic layer affixed thereto to provide additional impermeability. Two of the fabric layers may be affixed with the impermeable sides facing each other to provide an article capable of absorbing fluids from both sides, yet preventing fluids from penetrating from one side to the other. An optional plastic layer may be juxtaposed between the facing sides to provide a further fluid barrier. A method of disposing of such articles comprising contacting the articles with a sufficiently hot second liquid for a sufficient period of time to disperse or dissolve substantially the articles.

    摘要: A method for containing potentially infectious devices. The potentially infectious devices are deposited in a container which contains a monomer, a reducing agent and water. An oxidizing agent is later added to cause polymerization of the monomer to immobilize the devices, and to act as a disinfecting agent due in large part to the exothermic nature of the reaction. In an alternate embodiment, the composition contains a monomer, a thickener and water. Before use, this solution is admixed with an oxidizing and reducing agent and the thickened solution is poured into a container having disposed therein potentially infectious devices. Related methods, kits, devices, and compositions are also disclosed.
