PROBLEM TO BE SOLVED: To provide a functionalized silica and polymer composite that can be incorporated into a rubber system with excellent dispersion and minimal dust release and also can be incorporated into a predominantly SSBR rubber formulation without significantly affecting overall performance in an end product.SOLUTION: A functionalized silica product includes particles of a hydrophobated silica having a thin coating of an emulsion polymer. A ratio of the hydrophobated silica to the emulsion polymer is from about 4/1 to about 50/1. The functionalized silica product is in the form of a friable crumb or a powder that may be mixed into an elastomer formulation for a rubber article, such as a tire component.SELECTED DRAWING: Figure 1

    【課題】良好に分散しながらかつ最小限にしか粉塵を放出せずにゴム系に配合することが可能であり、最終製品の全体的な性能に顕著な影響を及ぼすことなく、SSBRを主成分とするゴム配合物に配合することもできる機能化シリカと重合体の複合体を提供する。【解決手段】機能化シリカ製品は、乳化重合体の薄い被膜を有する疎水化シリカ粒子を含む。疎水化シリカ対乳化重合体の比は約4/1〜約50/1である。機能化シリカ製品は、砕けやすいクラム又は粉末の形状をしており、ゴム物品、例えばタイヤ構成要素用のエラストマー配合物に混合することができる。【選択図】図1
