Abstract

An "on-demand" self-degrading polymer composition is disclosed comprising a polymer into which a substance is incorporated, the substance being unreactive when dry and forming or releasing an active substance upon exposure to water, the active substance acting to degrade the polymer. In preferred embodiments of the invention, the substance is a mixture of an inorganic superoxide and an inorganic peroxide. In particularly preferred embodiments of the invention, the substance is encapsulated by a material such as a hydrophilic polymer. Methods of manufacture of the composition and of producing a self-degrading polymer composition are disclose.
