실험 절차

2256 g (24 moles) of phenol, 2404 g (38.4 moles) of 40 wt. % formalin and 121.2 g (1.2 moles) of triethylamine were charged in a reactor provided with a reflux condenser and the mixture was allowed to react at 85° C. for two hours. Then, unreacted formalin was completely removed at that temperature under reduced pressure to obtain a resol having a solid concentration of 75 wt. %. The molecular weight of the resulting resol was measured by gel permeation method to reveal that it had 1-3 nuclei in average. The resol was used for the copolycondensation in following Preparation Examples 6 and 7.
