Beschreibung
Zusammenfassung:	This invention relates to compositions comprised of diene-based elastomers containing an antioxidant comprised of a combination of tris(nonyl phenyl) phosphite (TNPP) and tetramethylethylene diamine (TMEDA). The invention further relates a rubber composition and to a polystyrene composite containing such elastomer compositions. The invention additionally relates to articles of manufacture thereof, including tires and polystyrene based articles. In one embodiment, the invention relates to a process of recovery of diene-based elastomer(s) from an organic solvent solution thereof by steam stripping the organic solvent therefrom in the presence of a combination of the TNPP and TMEDA.
