The present invention aims to provide a rubber composition that exhibits excellent viscoelastic properties and in which inadequate mixing, inadequate dispersion, etc., are unlikely to occur between organic polymer materials derived from natural rubber and inorganic materials such as silica; and a silane coupling agent composition or the like used in such rubber composition. The silane coupling agent composition contains a silane compound represented by formula (1) [in the formula, R1 represents a hydrogen atom or a monovalent hydrocarbon group having at most 18 carbon atoms, R2 represents a divalent hydrocarbon group having at most 12 carbon atoms, X1 is selected from the group consisting of R3O- and R3C(=O)O- (in the formula, R3 represents a hydrogen atom, a monovalent hydrocarbon group having at most 18 carbon atoms, or a monovalent hydrocarbon group having one oxygen atom and at most 18 carbon atoms), X2 and X3 are each independently selected from the group consisting of elements exemplified by R4 and X1 (in the formula, R4 is a monovalent hydrocarbon group having at most 6 carbon atoms)], and/or a condensate thereof and a protein denaturing agent.
本发明提供不易产生来自天然橡胶的有机高分子材料与二氧化硅等无机材料的混合不良、分散不良等且发挥优异的粘弹性特性的橡胶组合物以及该橡胶组合物中使用的硅烷偶联剂组合物等。一种硅烷偶联剂组合物,是包含式(1)[式中,R1为氢原子或包含最多18个碳原子的一价烃基,R2为包含最多12个碳原子的二价烃基,X1选自R3O‑和R3C(=O)O‑(式中,R3为氢原子、或者包含最多18个碳原子的一价烃基、或者包含最多18个碳原子和至少1个氧原子的一价烃基),X2和X3各自独立地选自R4和X1中举出的要素(式中,R4为最多6个碳原子的一价烃基)]表示的硅烷化合物和/或其缩合物以及蛋白质变性剂而成的。
