Latest Patents

Stevens holds a patent for "Biodegradable composite polymeric articles comprising polyvinyl alcohol." This patent describes composite polymeric articles that may be in layer or film form. The invention comprises a larger portion of a polymer that is water-soluble at 20°C against a smaller proportion of a polymer that is substantially water-insoluble at that temperature. For instance, a layer product may feature a thin layer of insoluble polymer superimposed on a thicker layer of soluble polymer. Both polymers are conveniently polyvinyl alcohol, which is non-toxic and useful in various domestic applications, such as diaper backing sheets. The insoluble portion provides water resistance but negligible mechanical strength, while the soluble part offers the necessary mechanical strength. Upon dissolution of the soluble portion, the insoluble portion disintegrates mechanically. Articles can be produced through co-extrusion or molding techniques.
