Patent number: 9683066Abstract: A process for the continuous preparation of modified elastomeric polymers includes (i) providing and polymerizing at least one conjugated diene monomer and, optionally, one or more aromatic vinyl monomer in the presence of an anionic initiator and a compound according to Formula 1, e.g. 2,2-di-(2-oxolanyl)propane or a derivative thereof, to provide a living anionic polymer; and (ii) adding a “sulfanylsilane” compound to the living anionic polymer. Elastomeric polymers obtainable according to the above process and compositions including the elastomeric polymer and, optionally, further constituents such as oil, filler and/or vulcanizing agent are described. A process for the preparation of a cross-linked elastomeric polymer that includes adding a vulcanizing agent to the elastomeric polymer, as well as articles and compositions that include the elastomeric polymer, the cross-linked elastomeric polymer or both are described.Type: GrantFiled: March 20, 2012Date of Patent: June 20, 2017Assignee: TRINSEO EUROPE GMBHInventors: Silvia Valenti, Evemarie Hamann, Norbert Jantsch, Sven Thiele
