Embodiment 1-1
[0139] [Example 1-1] Synthesis of organosilicon compound 1
[0140] Into a 200 mL separable flask equipped with a stirrer, a reflux condenser, and a thermometer, 100 g of a dimethyl polysiloxane compound having a number average molecular weight of 13,600 and containing vinyl groups at both ends (0.015 moles in terms of functional groups of terminal vinyl groups) and 2.6 g of mercaptomethyltrimethoxysilane (0.015 mol of mercapto functional group) was heated to 90°C. 0.1 g of 2,2'-azobis-2-methylbutyronitrile was added thereto, and stirred at 90°C for 3 hours. according to 1 In the H-NMR measurement, it was confirmed that the peaks derived from the vinyl and mercapto groups of the raw materials completely disappeared, and a peak derived from the target organosilicon compound was detected instead, and the reaction was considered to be complete.
[0141] The obtained reaction product was a colorless transparent liquid with a number average molecular weight of 15200 and a viscos...
