Problems solved by technology

[0005] However, in this reaction, when a plurality of polyether groups are introduced into one molecule of siloxane, there are problems in that the reactivity decreases as the amount introduced increases, the reaction is not completed, and unreacted polyether groups remain.
In addition, there is also a problem that since the platinum catalyst is used, coloration due to the catalyst occurs, and it is not durable for use depending on the application.
In addition, in the presence of an organic functional group such as a mercapto group that causes addition poisoning, the reactivity of a polyether compound containing a reactive double bond with a Si-H group under a platinum catalyst decreases, making it difficult to introduce a polyether group.
That is, with this method, there is a problem that co-modification with polyether does not occur due to the difference in the selected organic functional group.

Embodiment 1

[0162] [Example 1] (Synthesis of polyether-modified methoxysiloxane containing mercapto group-1)

[0163] 25.0 g of 3-mercaptopropyl trimethoxysilane (12.7 × 10 -2 mol), 28.8g (4.25×10 -2 mol) and diacetone alcohol 17.0g, 2.67g of 0.05N hydrochloric acid aqueous solution (water: 14.8×10 -2 mol, hydrochloric acid: 1.34×10 -4 mol), and then matured for 2 hours.

[0164] (CH 3 O) 3 Si-C 3 h 6 -O(CH 2 CH 2 O) 11 CH 3 (19)

[0165] Next, add 1.91 g of a 1% methanol solution of sodium acetate (sodium acetate: 2.33×10 -4 mol), the temperature was raised to 70°C for 2 hours of aging.

[0166] Next, heating under reduced pressure at 100° C. and 10 mmHg for 2 hours, distilled off residual alcohol components and low boiling point components, and filtered to obtain a liquid organosiloxane 1 with a non-volatile content of 99.0% (yield: 42.7g, yield: 91%).

[0167] In this organopolysiloxane 1, in the above-mentioned average composition formula (1), Y is a 3-mercaptoprop...

Embodiment 2

[0170] [Example 2] (Synthesis of polyether-modified methoxysiloxane containing mercapto group-2)

[0171] 12.5 g of 3-mercaptopropyl trimethoxysilane (6.36 × 10 -2 mol) and 35.4g (6.36×10 -2 mol), 0.5 g of PERBUTYL-O [manufactured by NOF Corporation: tert-butyl peroxy-2-ethylhexanoate] was added with stirring, and aging was performed at 65° C. for 2 hours.

[0172] CH 2 =CH-CH 2 -O(CH 2 CH 2 O) 11 CH 3 (twenty three)

[0173] The resulting liquid was subjected to GPC (gel permeation chromatography) measurement in THF solvent. As a result, product peaks were confirmed within the retention time range of 28 minutes to 34 minutes. In addition, the peak derived from 3-mercaptopropyltrimethoxysilane almost disappeared in the retention time range of 36 minutes to 38 minutes. In addition, for the liquid generated above, the 1 H-NMR determination. As a result, the peak derived from the allyl group of the allylated polyether represented by the above formula (23) existin...
