    Abstract: The invention provides chain-coupled polymeric alkoxide compounds for use as the elastomeric component in vulcanizable elastomeric compositions comprising silica, carbon black or mixtures thereof. In particular, the invention provides anionically polymerized polymers having polymer chain living ends that are functionalized with alkoxide groups and coupled together by a metal or nonmetal atom. The polymeric alkoxide compounds have an initial high viscosity for ease of handling prior to compounding, a stable viscosity during storage, and a decreased compound viscosity for better filler dispersion and improved mixing efficiency. The invention further provides a pneumatic tire having at least one component produced from the vulcanizable elastomeric composition of the invention.

    Abstract translation: 本发明提供了用作可硫化弹性体组合物中的弹性体组分的链偶联聚合物醇盐化合物,其包含二氧化硅,炭黑或其混合物。 特别地,本发明提供具有聚合物链活性末端的阴离子聚合聚合物,该末端用烷氧基基团官能化并通过金属或非金属原子偶联在一起。 聚合物醇盐化合物具有初始高粘度,以便在配混之前易于处理,在储存期间稳定的粘度,以及降低的化合物粘度以获得更好的填料分散和改善的混合效率。 本发明还提供一种充气轮胎,其具有由本发明的可硫化弹性体组合物制成的至少一种组分。
