A silane compound of the following formula (1) having two or more protected functional groups
A-R—Si(CH
3
)
n
X
3-n
(1)
wherein A represents a group of the following formula
wherein R
1
, R
2
and R
3
each independently represent a monovalent hydrocarbon group having 1 to 10 carbon atoms, a is an integer of 1 to 10, and b is an integer of 1 to 10, or
wherein R
1
, R
2
and R
3
are as defined above, R represents a linear or branched, divalent hydrocarbon group having 2 to 10 carbon atoms, X represents a halogen atom or an organoxy group having 1 to 10 carbon atoms, and n is 0, 1 or 2 is prevented from the reaction of the functional groups per self when undergoing modification or treatment. When the protection is removed after introduction of the protected functional groups, quantitative and efficient introduction of the two or more functional groups is ensured, resulting in more developed effects of modification and addition.
具有以下式(1)的两个或更多受保护功能基团的硅烷化合物A-R—Si(CH3)nX3-n(1)其中A代表以下式的一个基团其中R1、R2和R3分别独立地代表具有1至10个碳原子的一价碳氢基团,a为1至10的整数,b为1至10的整数,或其中R1、R2和R3如上定义,R代表具有2至10个碳原子的线性或支链二价碳氢基团,X代表卤素原子或具有1至10个碳原子的有机氧基团,n为0、1或2在经过改性或处理时,防止每个自身的功能基团发生反应。在引入受保护功能基团后去除保护时,确保了两个或更多功能基团的定量和高效引入,从而产生更加发展的改性和添加效果。
