Abstract
Abstract of the Disclosure ABSTRACT OF THE DISCLOSURE Gas generating and releasing articles consisting essentially of a polymer and a gas generating solid dispersed therein are described. The article generates and releases a gas in response to moisture and in the absence of an acid, a polymer that degrades to produce an acid, a compound that generates an acid in response to humidity, a hygroscopic compound, and an oxidant. The article may also generate and release a gas in response to energy.
Claims68
A sulfur dioxide gas generating and gas releasing monolayer article consisting essentially of between 30.0% and 99.9% by weight of a polymer and between 0.1% and 70.0% by weight of a gas generating solid dispersed in the polymer, wherein the article is free of an acid, a polymer that degrades to produce an acid, a compound that generates an acid in response to humidity, a hygroscopic compound, and an oxidant, the gas generating solid being capable of generating and releasing sulfur dioxide gas upon exposure of the article to moisture, wherein the article has a thickness of between about 5 μm and 1000 μm.
A gas generating and gas releasing monolayer article comprising between 30.0% and 99.9% by weight of a first polymer and between 0.1% and 70.0% by weight of a gas generating solid dispersed in the polymer, wherein the article is free of an acid, a second polymer, a compound that generates an acid in response to humidity, a hygroscopic compound, and an oxidant, the gas generating solid consisting essentially of one or more gas generating and releasing components with at least one component being capable of generating and releasing at least one gas upon exposure of the article to moisture, wherein the article has a thickness of between about 5 μm and 1000 μm.
