Title:
LINEAR ORGANOPOLYSILOXANE HAVING DIFFERENT FUNCTIONAL GROUPS AT BOTH TERMINALS, AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2017/094392
Kind Code:
A1
Abstract:
[Problem] The present invention addresses the problem of providing: a different-terminal functional organopolysiloxane compound, in which different functional groups are provided respectively at both terminals of a polysiloxane, and which has a satisfactory siloxane content; and a method for producing the compound. The present invention also provides: a polysiloxane compound having a terminal amino group and another terminal functional group; and a method for producing the polysiloxane compound. [Solution] The present invention provides a silicone compound which is represented by general formula (I) and has different functional groups respectively at both terminals. The silicone compound has a functional group that is unreactive with an organometallic compound, a functional group that has radical polymerizability or a functional group that is reactive with an organometallic compound (a first organic functional group) or an atom at one terminal of a diorganopolysiloxane (i.e., a terminal A in general formula (I)) and also has a hydrogen atom or a group selected from the alternatives for the aforementioned organic functional group (a second organic functional group) or an atom, which is a functional group or atom different from that located at the aforementioned terminal (the terminal A), at the other terminal (i.e., a terminal B in general formula (I)). The present invention also provides a method for producing a silicone compound represented by general formula (I). This production method comprises the steps of: reacting a cyclic siloxane or a disiloxane each having a first organic functional group with an organometallic compound; and reacting a metal silicate compound produced by the aforementioned step with a halogenated silyl compound having a second organic functional group.
