Procedure
The amount of the phenol (A) added after the conversion of 3,3,5-trimethylcyclohexanone (B) has reached 90 mol % or over is preferably such that the total molar amount of the phenol (A) added (the total phenol (A) consisting of the phenol (A) introduced in carrying out the pre-reaction, the phenol (A) dropped in the form of a liquid mixture with 3,3,5-trimethylcyclohexanone (B) in the reaction mixture and the phenol (A) added after the conversion of 3,3,5-trimethylcyclohexanone (B) has reached 90 mol % or over) is 5 to 10 times, especially 6 to 8 times, based on the molar amount of 3,3,5-trimethylcyclohexanone (B). When the amount of the phenol (A) added after the conversion of 3,3,5-trimethylcyclohexanone (B) has reached 90 mol % or over falls within the above range, not only can the rise of the viscosity of the reaction mixture be suppressed to thereby ensure efficient operation but also the desired 3,3,5-trimethylcyclohexylidenebisphenol can be obtained at high yield. The degree of conversion (%) of 3,3,5-trimethylcyclohexanone (TMC) is defined by the formula:
