Abstract
[Problem] To provide a stabilizer for suppressing generation of silane from a polysilane composition and a method for suppressing generation of silane. To provide a method for inactivating a polysilane, and a polysilane inactivated treatment composition. [Means for Solution] A stabilizer represented by the following formula for suppressing generation of silane from a polysilane composition: CH2═CH—R1 wherein R1 is C3-20 linear, branched or cyclic alkyl group, C2-15 linear or branched alkenyl group or C7-20 aryl group substituted with alkenyl group. [Selected Drawing] None

A method for suppressing generation of silane, comprising making a stabilizer represented by the following formula coexist with a polysilane:
- wherein R1 is
- C3-20 linear, branched or cyclic alkyl group,
- C2-15 linear or branched alkenyl group or
- C7-20 aryl group substituted with alkenyl group.
A method for inactivating a polysilane containing waste liquid comprising:
- mixing the polysilane containing waste liquid with a stabilizer represented by the following formula:
- wherein R1 is
- C3-20 linear, branched or cyclic alkyl group,
- C2-15 linear or branched alkenyl group or
- C7-20 aryl group substituted with alkenyl group.
A polysilane inactivated treatment composition comprising:
- a stabilizer represented by the following formula:
- wherein R1 is
- C3-20 linear, branched or cyclic alkyl group,
- C2-15 linear or branched alkenyl group or
- C7-20 aryl group substituted with alkenyl group;
- and
- a solvent.
