The present invention is directed to compounds represented by the formula I: wherein Rcomprises a hydrogen atom or an alkyl group having 1 to 2 carbon atoms; wherein Rcomprises an alkylene group, an arylene group, or a heterocyclic group; and wherein R, R, R, R, R, and Rare identical or different and comprise a hydrogen atom, an alkyl group, an aryl group, or an alkylaryl group.

Triazinane derivatives and methods of making them

The present invention is directed to compounds represented by the formula: Formula (i) wherein Rcomprises a hydrogen atom or an alkyl group having 1 to 2 carbon atoms; wherein Rcomprises an alkylene group, an arylene group, or a heterocyclic group; and wherein M comprises a monovalent metallic cation such as sodium, lithium, or potassium; or a multivalent metallic cation such as zinc, nickel, iron, titanium, or cobalt; or an ammonium or alkyl ammonium cation derived by addition of proton (s) to a nitrogenous base.

Triazinanes and methods of making them

The invention relates to a phased rubber composition and tire tread thereof intended for heavy duty service such as for example a truck tire. The phased rubber composition is comprised of the product of blending a first rubber phase comprised of cis 1,4-polybutadiene rubber and reinforcing filler comprised of rubber reinforcing carbon black and a second rubber phase comprised of natural cis 1,4-polyisoprene rubber and reinforcing filler comprised of precipitated silica.

Phased rubber composition and tire with tread

The invention relates to pneumatic tires having treads of a cap/base configuration where the outer tread cap rubber layer contains lugs with intervening grooves which extend to the running surface of the tread cap and wherein at least one of said grooves is contained in a rubber block within the tread. For this invention, the tread groove-containing rubber block joins the tire carcass and extends radially outward through the tread base rubber layer and into the outer tread cap rubber layer.

Tire

The invention relates to a tire having a rubber tread of a circumferentially zoned tread including stratified lateral tread zones and peripheral sidewall extensions. The tread zones are comprised of three circumferential load bearing zones, with each zone containing a portion of the running surface of the tread, comprised of an intermedial zone positioned between and two stratified lateral tread zones together and, in addition, peripheral sidewall extensions. The intermedial and stratified lateral zones are comprised of rubber compositions having differentiated 100&#xb0; C. hot rebound physical properties. The intermedial rubber zone, or layer, overlays a tread base rubber layer and underlies the lateral tread layer zones. The lateral tread zones are stratified in a sense of being separated from each other and also separated from the from the tread base rubber layer by the intermedial rubber layer. The tread includes a peripheral carbon black rich rubber layer as a sidewall extension which extends radially outward from the outer tire sidewall to thereby join a portion of the peripheral tread zone rubber layer and extends to and includes a portion of the running surface of the tread.

Tire with circumferentially zoned tread including stratified lateral zones and peripheral sidewall extensions

The invention relates to a tire with circumferentially zoned tread including peripheral sidewall extensions. The tread zones are comprised of three circumferential load bearing zones, with each zone containing a portion of the running surface of the tread, comprised of an intermedial rubber zone positioned between and extending beneath two stratified lateral tread rubber zones and, in addition, peripheral sidewall extensions. The tread configuration contains a carbon black reinforced tread base rubber layer underlying the intermedial tread rubber zone. The lateral tread rubber zones are therefore spaced apart from each other with the intermedial tread zone therebetween and also at least partially spaced apart from the tread base rubber layer with the intermedial tread zone therebetween. The tread includes a peripheral carbon black reinforced rubber layer as an extension of the tire sidewall which extends radially outward from the outer tire sidewall to thereby join a portion of a lateral tread zone which may extend to and include a portion of the running surface of the tread.

Tire with rubber tread of intermedial and lateral zones with periperial sidewall extensions

The invention relates to a pneumatic rubber truck tire having a circumferential stratified dual cap rubber tread comprised of an outer tread cap and underlying tread sub cap. The underlying tread sub cap rubber layer is provided to support the outer tread cap rubber layer with similar physical properties. Both of the tread cap rubber compositions are comprised of a combination of natural cis 1,4-polyisoprene and dual cis 1,4-polybutadiene elastomers and contain reinforcing fillers comprised of precipitated silica and rubber reinforcing carbon black. The tread cap rubber compositions differ from each other by containing different levels of the individual cis 1,4-polybutadiene rubbers and by containing different rubber reinforcing carbon blacks and precipitated silica.
