| 20100216939 | TIRE WITH TREAD OF POLYBUTADIENE RUBBER - Pneumatic rubber tire with an outer, circumferential tread comprised of specialized cis 1,4-polybutadiene rubber based silica/carbon black reinforced rubber composition. | 08-26-2010 |
| 20120196976 | USE OF ARYL DINITRILE OXIDES IN ADHESIVE COMPOSITION - The invention relates to the use of an adhesive composition between a vulcanized rubber part and an uncured or prevulcanized or vulcanized rubber part, based on at least one highly unsaturated elastomer chosen from the group formed by natural rubber, polyisoprene, polybutadiene, styrene-butadiene, styrene-isoprene and butadiene-isoprene copolymers and styrene-butadiene-isoprene terpolymers, an aliphatic solvent and a “curing” system comprising at least one stable aryl dinitrile oxide compound. | 08-02-2012 |
| 20140275404 | CONJUGATED DIENE BASED POLYMER, AND POLYMER COMPOSITION CONTAINING THE POLYMER - The present invention relates to a conjugated diene based polymer comprising a monomer unit derived from at least one conjugated diene selected from 1,3-butadiene and isoprene and a monomer unit derived from a compound having two conjugated carbon-carbon double bonds and one or more non-conjugated carbon-carbon double bond. | 09-18-2014 |
| 20150133600 | METHOD FOR PRODUCING CONJUGATED DIENE RUBBER - A method for producing a conjugated diene rubber is provided which includes the steps of: (a) forming a polymer block (A) by using a polymerization initiator in an inert solvent, the polymer block (A) having an active terminal and containing a specific amount of an isoprene monomeric unit and a specific amount of an aromatic vinyl monomeric unit; (b) forming a polymer block (B) having an active terminal and containing a specific amount of a 1,3-butadiene monomeric unit and, as needed, a specific amount of an aromatic vinyl monomeric unit, thereby obtaining a conjugated diene polymer chain having an active terminal and having the polymer block (A) and a polymer block (B); (c) bringing a specific amount of a predetermined denaturant into reaction with the active terminal of the conjugated diene polymer chain having the active terminal. | 05-14-2015 |
| 20160115269 | PROCESS FOR PRODUCING HYDROGENATED BLOCK COPOLYMER, HYDROGENATED BLOCK COPOLYMER OBTAINED BY THE PROCESS, AND COMPOSITION THEREOF - The present invention relates to a method for producing a hydrogenated block copolymer, including the steps of: (a) forming a block copolymer by allowing a living polymer having a specific structure to react with a tetra- or more functional silane coupling agent; (b) hydrogenating the block copolymer to form a hydrogenated block copolymer; (c) isolating the resultant hydrogenated block copolymer; and (d) deactivating a functional group in the silane coupling agent and/or an unreacted functional group present in a coupling agent residue in the block copolymer or the hydrogenated block copolymer prior to the step (c), in which the number of functional groups derived from the coupling agent in the hydrogenated block copolymer recovered in the step (c) is 1.5 or less per block copolymer molecule; a hydrogenated block copolymer obtained by the method; and a composition containing the hydrogenated block copolymer. | 04-28-2016 |
