This invention relates to hydrolysable silanes useful in the modification of elastomers, and as coupling agents for diene elastomer compositions containing a filler. In particular the invention relates to novel hydrolysable silanes containing a tertiary amine group and an ether or thioether linkage.

Hydrolysable silanes

This invention relates to hydrolysable silanes useful in the modification of elastomers, and as coupling agents for diene elastomer compositions containing a filler. In particular the invention relates to novel hydrolysable silanes containing an aziridine ring herein named (Az).

This invention relates to the treatment of a carbon based filler with a hydrolysable silane to modify the surface of the filler. It also relates to a carbon based filler modified by treatment with a hydrolysable silane, and to polymer compositions containing such a modified carbon based filler.

Treatment of filler with silane

This invention relates to hydrolysable silanes useful in the modification of elastomers, and as coupling agents for diene elastomer compositions containing a filler. In particular the invention relates to novel hydrolysable silanes containing a piperazine ring and an ether or thioether linkage.

Hydrolysable silanes and elastomer compositions containing them

The present invention relates to a curable rubber composition comprising an organic elastomer, a filler and at least one curing agent for the elastomer. Such curable rubber compositions are widely used in the production of cured rubber articles, such as tires, belts and hoses. The composition contains a branched silicone resin having Si-bonded hydroxyl groups or azo groups. This may lead to a reduction in the mixing energy required for processing, particularly in the energy required in the first (non-productive) mixing phase to give good dispersion of the filler in the organic elastomer. Use of the branched silicone resin can also accelerate cure (vulcanization), thus reducing the required cure time or reducing the amount of cure accelerator required.
