Preparation Example 3. 2,2-bis[4-trimethylsilyloxy-3,5-bis(trimethylsilyloxymethyl)-phenyl]propane (monomer K). a) 2,2-bis[4-hydroxy-3,5-di(hydroxymethyl)phenyl)]propane. 114.4 of bisphenol A (2,2-bis[4-hydroxyphenyl)]propane) were initially charged in a mixture of 450 g of water and 50 g of NaOH. While cooling (Tmax=25°C), 350 g of 30% formaldehyde solution were added dropwise. After continued reaction at room temperature for 1 h, a clear solution was obtained. The mixture was neutralized by adding solid CO2. The resulting solution was saturated with sodium chloride and extracted 3 times with butanol. The extracts were concentrated on a rotary evaporator at 50°C down to 5 mbar. The product was used in the next step without further purification. colorless oil. 1H-NMR 400 MHz, CDCl3, 25°C, TMS δ [ppm] = 7.03 (s, 4 H, Aromat); 5.00 (s, 6 H, -OH (breit)); 4.63 (s, 8H, -CH2-); 1.60 (s, 6 H, C-CH3). | [References]
