说明

一般說明

Diethoxy(methyl)vinylsilane is an organosiloxane with a reactive vinyl group. It has a good toughness which is highly thermo-stable and a good film former. It can be converted into a highly cross-linked polymer through thermal polymerization reaction.[1][2][3]

應用

Diethoxy(methyl)vinylsilane can be used to prepare benzocyclobutene(BCB) functionalized siloxanes for the development of encapsulating resins in microelectronics industry.[2] It may be used in the preparation of polysiloxane modified tetraphenylethene(PTPESi) which finds potential application as a sensor for vapour phase detection of explosives.[4] It may also be used in the surface modification of silica matrix that enables better chromatographic properties in cation-exchange process.[2]
