| titleOfInvention | Method for producing silicone polymer |
| abstract | PROBLEM TO BE SOLVED: To provide a method for producing a silicone polymer which is liquid at room temperature, has little absorption of ultraviolet rays, is transparent, and has excellent ultraviolet curability. SOLUTION: It is represented by the general formula (1) R 1 Si (OR 2 ) 3 ... (1) (in the formula, R 1 represents a 3-methacryloxypropyl group and R 2 represents a hydrocarbon group). 88 to 92 mol% of the compound to be used, and the general formula (2) R 3 Si (OR 4 ) 3 ... (2) (in the formula, R 3 represents a methyl group and R 4 represents a hydrocarbon group). Compound represented by 8 to 12 mol% of silane compound, in the presence of tetramethylammonium hydroxide, 0.5 to 1.5 times by weight of isopropyl alcohol and 2 of methyl isobutyl ketone with respect to the total amount of silane compounds. .0 to 3.0 times by weight, 2.5 to 3.3 mol times of water, and react. The weight average molecular weight is 2000 to 2600, the terminal is a silanol group, and 5 A method for producing a silicone polymer that is liquid at ~ 40 ° C. [Selection diagram] None |
