Definitions
- the present invention relates to a novel vinyl silane compound, particularly a vinyl silane compound capable of reversibly causing a change between a dimer and a monomer by heat and a method for producing the same.
- vinylsilane compound having two vinylsilyl groups in the molecule in particular, vinyldiorganosilyl group such as vinyldimethylsilyl group
- 1,3-divinyl-1,1,3,3-tetramethyldisiloxane 1,3-divinyl-1,1,3,3-tetraphenyldisiloxane, dimethylpolysiloxane blocked with dimethylvinylsiloxy group at both ends of the molecular chain, and the like. Since these compounds have a vinylsilyl group, it is possible to carry out a hydrosilylation addition reaction with hydrosilane or organohydrogenpolysiloxane.
- an object of the present invention is to provide a vinylsilane compound capable of imparting new properties to an organosilicon resin by connecting vinylsilyl groups with a structure other than a siloxane bond.
- the present invention provides the following vinylsilane compound. ⁇ 1> The following general formula (1)
- each A is independently a divalent hydrocarbon group having 1 to 6 carbon atoms
- Y is each independently a substituted or unsubstituted monovalent hydrocarbon group having 1 to 12 carbon atoms.
- each A is independently a methylene group, an ethylene group or a trimethylene group.
- the vinyl silane compound of the present invention may be a mixture of various vinyl silane compounds having different structures as long as the structure is in the range of the above formula (1).
- the present invention also provides the following method for producing a vinylsilane compound.
- ⁇ 4> The following formula (2) (Wherein A is a divalent hydrocarbon group having 1 to 6 carbon atoms, Y is independently a substituted or unsubstituted monovalent hydrocarbon group having 1 to 12 carbon atoms, and X is a halogen atom. .)
- ⁇ 5> The method for producing a vinylsilane compound according to ⁇ 4>, wherein A is a methylene group, ethylene group or trimethylene group, Y is a methyl group, and X is a Cl atom or a Br atom.
- the vinylsilane compound of the present invention has a vinylsilyl group
- hydrosilylation addition reaction with hydrosilane or organohydrogenpolysiloxane is possible.
- the vinylsilane compound of the present invention and a bifunctional organohydrogenpolysiloxane having two silicon-bonded hydrogen atoms (SiH groups) in the molecule in particular, one SiH group at each end of the molecular chain
- SiH groups silicon-bonded hydrogen atoms
- an organosilicon resin such as an organopolysiloxane having a certain degree of molecular weight (degree of polymerization) can be obtained.
- This organosilicon resin has thermoplasticity because the dicyclopentadiene skeleton derived from the vinylsilane compound of the present invention reversibly changes between a dimer and a monomer by heat. Therefore, the vinylsilane compound of the present invention is a suitable compound as a compound that can impart thermoplasticity to the organosilicon resin.
- Example 1 is a 1 H-NMR chart of a vinylsilane compound obtained in Example 1.
- the vinylsilane compound of the present invention is a compound represented by the above general formula (1) (that is, a bissilane compound having two vinylsilyl groups on a dicyclopentadiene skeleton).
- a divalent hydrocarbon group having 1 to 6 carbon atoms, particularly 1 to 4 carbon atoms, particularly 1 to 3 carbon atoms represented by A is represented by — (CH 2 ) n
- a linear alkylene group represented by-(n is an integer of 1 to 6, particularly 1 to 4, particularly 1 to 3) is preferable.
- - (CH 2) - methylene group represented by, - (CH 2) 2 - ethylene (dimethylene group) represented by, or - (CH 2) 3 - trimethylene group represented by are preferred.
- the substituted or unsubstituted monovalent hydrocarbon group represented by Y having 1 to 12 carbon atoms, preferably 1 to 6 carbon atoms may be a methyl group, an ethyl group, or propyl group.
