Uncured rubber compositions containing aromatic furazan oxides

摘要

Uncured rubber compositions containing fused aromatic furazan oxides exhibit improved processability and reduced viscosity. Useful furazan oxides have both carbons of the furazan ring as part of a fused aromatic ring and include benzofurazan oxide and its methyl and methoxy analogs. Improvements in processability, green strength and liquification of NR can be achieved through use of these furazan oxides in uncured rubber compositions.
