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. Filled rubber vulcanizates containing aromatic furazan oxides exhibit many improved properties such as increased filler-rubber interaction and decreased hysteresis. Useful furazan oxides have both carbons of the furazan ring as part of a fused aromatic ring. Typical examples are benzofurazan oxide an its methyl and methoxy analogs. Tires made from the inventive vulcanizates show lower running temperatures and improved rolling resistance.
