20130025760 | RADIAL TIRE FOR HEAVY LOAD - The present invention relates to a radial tire for a heavy load comprising a bead core, a carcass ply layer, an inner liner A layer, a belt and a tread, wherein the following relational equation (I): | 01-31-2013 |
20130096267 | PROCESS FOR PRODUCING FUNCTIONALIZED POLYMERS - A method for preparing a functionalized polymer, the method comprising the steps of (a) polymerizing monomer in the presence of a coordination catalyst to form a polymer, (b) inhibiting said step of polymerizing with a Lewis base, and (c) reacting the polymer with a functionalizing agent. | 04-18-2013 |
20130116360 | MIXING OF TELECHELIC RUBBER FORMULATIONS - The present disclosure is directed to methods for preparing rubber compositions where those rubber compositions comprise at least one telechelic polymer and at least one filler. The methods make use of a mixer that includes a mixing chamber and at least one rotor with wings of specified configuration. Use of the disclosed methods yields a rubber composition with improved properties including an improved dispersion index after master batch mixing as compared to the same rubber composition mixed using standard 4 wing mixers. | 05-09-2013 |
20130172446 | INTERMESHING MIXING OF FILLER AND POLYMER SOLUTION MASTERBATCH - A method includes: mixing a polymer cement and a filler to form a solution masterbatch; optionally drying the solution masterbatch to form a crumb polymer composition; mixing a low viscosity polymeric or oligomeric liquid into the solution masterbatch or crumb polymer composition; and intermeshing mixing the solution masterbatch or crumb polymer composition. | 07-04-2013 |
20130172461 | RUBBER COMPOSITION FOR GOLF BALL - The invention provides a rubber composition for golf balls which includes: (A) a base rubber containing a polybutadiene having a cis-1,4 bond content of at least 60 wt %; (B) an unsaturated carboxylic acid and/or a metal salt thereof; (C) an anthranilic acid derivative of the general formula | 07-04-2013 |
20130190423 | Rubber Compositions Including Metal Phosphate Esters - A composition includes a diene rubber and a metal phosphate ester of the formula: | 07-25-2013 |
20130197138 | RUBBER COMPOSITION FOR GOLF BALL - Rubber composition for golf balls which includes: (A) a base rubber containing a polybutadiene having a cis-1,4 bond content of at least 60 wt %; (B) an unsaturated carboxylic acid and/or a metal salt thereof; (C) an anthranilic acid derivative of the general formula | 08-01-2013 |
20130197140 | ESTERS OF CYCLOHEXANE POLYCARBOXYLIC ACIDS AS PLASTICIZERS IN RUBBER COMPOUNDS - It has been discovered that the use of a plasticizer, an ester of a cyclohexanepolycarboxylic acid, especially a 1,2-cyclohexanedicarboxylic acid ester, that is environmentally non-toxic, can replace environmentally unfriendly phthalate plasticizers, such as dioctyl phthalates used in vulcanizable rubber compositions, especially for tires, on a one to one weight basis (phr) without sacrificing beneficial rubber properties. | 08-01-2013 |
