Provided is a novel organosilicon compound which functions as a silane coupling agent (wetter) that enables a silicone to be filled with a large quantity of a filler.
The organosilicon compound is represented by a general formula (1)
wherein, R1 represents a hydrogen atom, or an unsubstituted or substituted monovalent hydrocarbon group, R2 to R4 represent identical or different unsubstituted or substituted monovalent hydrocarbon groups, each R5 represents, independently, a hydrogen atom, or an unsubstituted or substituted monovalent hydrocarbon group, each R6 represents, independently, an identical or different unsubstituted or substituted monovalent organic group, m represents an integer from 0 to 4, and n represents an integer from 2 to 20; as well as a method of producing the above organosilicon compound, wherein a one end organohydrogensilyl-terminated organopolysiloxane is produced by reacting an organohydrogensiloxane with a vinylsilane or an alkenyltriorganooxysilane in the presence of a hydrosilylation catalyst, and optionally this one end organohydrogensilyl-terminated organopolysiloxane is then reacted with an alkene in the presence of a hydrosilylation catalyst.
提供了一种新型的有机硅化合物,其作为硅烷偶联剂(润湿剂),使硅橡胶能够填充大量填料。
