Abstract
Methods of modifying polymeric compositions include exposing a polydiorganosiloxane polyoxamide copolymer composition to UV radiation at or below the B spectral range to effect de-polymerization of at least a portion of the polydiorganosiloxane polyoxamide copolymer. The polydiorganosiloxane polyoxamide copolymer composition may include additional components and the modified polydiorganosiloxane polyoxamide copolymer compositions can be included into articles.
