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. A process of preparing a polystyrene composite comprising the step of polymerizing styrene in the presence of 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) in a weight ratio of TNPP to TMEDA in a range of from about 4/1 to about 50/1. 2. The process of claim 1 wherein said diene-based elastomer is at least one of polybutadiene and polyisoprene.
