Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. An elastomer composite comprised of at least one diene-based elastomer containing an antioxidant comprised of a combination of tris(nonyl phenyl) phosphite (TNPP) and tetramethylethylene diamine (TMEDA) in a weight ratio of TNPP to TMEDA in a range of from about 4/1 to about 50/1. 2. The elastomer composite of claim 1 wherein said diene-based elastomer is comprised of at least one of polybutadiene and polyisoprene. 3. A polystyrene composite comprised of polystyrene containing the elastomer composite of claim 1 . 4. A polystyrene composite comprised of polystyrene and elastomer composite of claim 2 . 5. An article of manufacture having a component comprised of said polystyrene composite of claim 3 comprised of polystyrene and an elastomer composite comprised of diene-based elastomer containing an antioxidant comprised of a combination of tris(nonyl phenyl) phosphite (TNPP) and tetramethylethylene diamine (TMEDA). 6. An article of manufacture having a component comprised of said elastomer composite of claim 1 . 7. The article of manufacture of claim 6 comprised of a tire. 8. An article of manufacture comprised of a tire having a component comprised of a rubber composition containing at least one of polyisoprene and polybutadiene elastomer(s) prepared by steam stripping said elastomer(s) from an organic solvent solution thereof at an elevated temperature of water which contains such solvent solution wherein said elastomer during said steam stripping process contains an antioxidant comprised of a combination of tris(nonyl phenyl) phosphite (TNPP) and tetramethylethylenediamine (TMEDA).
