Abrégé

The present application relates to biodegradable elastomeric articles and methods for their production. In particular, the application relates to a method for the production of a biodegradable elastomeric article, the method comprising: preparing a solubilised biodegradation additive using a pH increasing agent and optionally a dispersant or surfactant; preparing an elastomeric film-forming composition by combining an elastomer and one or more cross-linking agents with the solubilised biodegradation additive; dipping a former into the elastomeric film-forming composition to produce a layer of the elastomeric film-forming composition on the former; drying and/or curing the layer of elastomeric film-forming composition on the former to produce the elastomeric article; and removing the elastomeric article from the former. The application also relates to an elastomeric film-forming composition for the production of biodegradable elastomeric articles, and biodegradable elastomeric article including as prepared by the method and from the film-forming composition.
