Publication number: 20160369015Abstract: The present invention relates to backbone-modified elastomeric polymers. The invention also relates to polymer compositions comprising such modified polymers, to the use of such compositions in the preparation of vulcanized polymer compositions, and to articles prepared from the same. The modified polymers are useful in the preparation of vulcanized, i.e. cross-linked, elastomeric compositions having relatively low hysteresis loss. Such vulcanized compositions are useful in many articles, including tire treads having low heat build-up, low rolling resistance, good wet grip and ice grip, in combination with a good balance of other desirable physical and chemical properties, for example, abrasion resistance and tensile strength. Moreover, the unvulcanized poly mer compositions exhibit excellent processability.Type: ApplicationFiled: December 9, 2013Publication date: December 22, 2016Applicant: Trinseo Europe GmbHInventors: Christian Doring, Sven Thiele, Daniel Heidenreich
