Synthetic example 1
[0091] Synthesis Example 1 : Production of siloxane copolymer (A)
[0092]30 parts by weight of phenyltriethoxysilane, 50 parts by weight of tetraethoxysilane and 20 parts by weight of acryloyloxypropyl trimethoxysilane were respectively put into a flask equipped with a cooling tube and a stirrer as a reactive silane, and 100 parts by weight of ethanol was put in as a solvent, and it stirred slowly after replacing with nitrogen. After adding 40 parts by weight of ultrapure water and 3 parts by weight of oxalic acid as a catalyst to the reaction solution, the mixture was stirred again slowly. One hour later, the temperature of the reaction solution was raised to 60° C., and the temperature was maintained for 10 hours to carry out solution polymerization, and then cooled to normal temperature to complete the reaction. Further, it was quenched to below 0° C. to precipitate the reactants. In addition, after removing the supernatant containing unreacted silane, the alcohol solve...
Synthetic example 2
[0093] Synthesis example 2 : Production of siloxane copolymer (B)
[0094] 30 parts by weight of phenyltriethoxysilane, 50 parts by weight of tetraethoxysilane and 20 parts by weight of acryloyloxypropyl trimethoxysilane were respectively put into a flask equipped with a cooling tube and a stirrer as a reactive silane, and The solvent was not put in, and it stirred slowly after replacing with nitrogen. After adding 40 parts by weight of ultrapure water and 2 parts by weight of nitric acid as a catalyst to the reaction solution, the mixture was stirred again slowly. One hour later, the temperature of the reaction solution was raised to 60° C., and the temperature was maintained for 10 hours to perform bulk polymerization, and then cooled to normal temperature to complete the reaction. Further, it was quenched to below 0° C. to precipitate the reactants. In addition, after removing the supernatant containing unreacted silane, the alcohol solvent and residual moisture generat...
Synthetic example 3
[0095] Synthesis example 3 : Production of siloxane copolymer (C)
[0096] In the above Synthesis Example 1, 40 parts by weight of diphenyldimethoxysilane, 40 parts by weight of tetraphenoxysilane and 20 parts by weight of vinyltriethoxysilane were respectively put into a flask equipped with a cooling tube and a stirrer as Reactive silane was carried out in the same manner as in Synthesis Example 1 above except for this. As a result of the final GPC analysis, a siloxane copolymer having a polystyrene-equivalent weight average molecular weight (MW) of 13,000 was produced.
