Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Suitable polyethers of polyhydric phenols excluding the diglycidyl ethers noted above, include for example, the polyglycidyl polyethers of dihydric phenols including mononuclear phenols such as resorcinol, catachol, hydroquinone and methyl resorcinol and polynuclear phenols such as 4,4'-dihydroxy benzophenone, 1,5-dihydroxy naphthalene and particularly the alkylene bis-phenols such as 2,2-bis(4-hydroxyphenyl)propane, 1,1-bis(4-hydroxyphenyl)propane, 1,1-bis(4-hydroxyphenyl)ethane, 1,1-bis(4-hydroxyphenyl)isobutane, 2,2-bis(4-hydroxyphenyl)butane, 2,2-bis(4-hydroxy-2-methylphenyl)propane, 1,1-bis(4-hydroxyphenyl)-2-methyl propane, 3,3-bis(4-hydroxyphenyl)pentane, 1,1-bis(4-hydroxyphenyl)2-ethylhexane, and bis(4-hydroxyphenyl)methane.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 121 g (0.5 mol) of 2,2-bis-(4-hydroxyphenyl)-butane, 22 g of an acid-activated fuller's earth and 90 g (1.6 mol) of isobutylene are stirred in an autoclave for 6 hours at 180° C. After cooling, the reaction mixture is taken up in 150 ml of toluene, the catalyst filtered off and the solvent evaporated. The residue is fractionated through a 1 meter glass-packed column, giving at a boiling temperature of 155° to 160° C./12 Torr 37 g of a fraction from which 24.8 g (20 % of the theoretical) of 5-hydroxy-1,3,3-trimethyl-1-ethyl indane (V) melting at 86° C. are obtained by recrystallisation from 90 ml of petroleum ether. ##STR23## After cooling the catalyst filtered off the solvent evaporated

Procedure: A methylene chloride solution of a bisphenol B oligomer having a chloroformate group at its molecular terminal was obtained in the same manner as that in Manufacturing Example 1 except that the bisphenol E was replaced by 65.8 g (0.272 mol) of 2,2-bis(4-hydroxyphenyl)butane (BisB), the amount of triethylamine was changed to 53.8 g (0.533 mol), and the methylene chloride solution of phosgene was replaced by a solution in which 52.7 g (0.533 mol) of phosgene was dissolved in 225 mL of methylene chloride in Manufacturing Example 1. The obtained solution had a chloroformate concentration of 0.99 mol/L, a solid concentration of 0.21 kg/L and an average number of repeating units (n′) of 1.21. A content of an amide compound in the obtained BisB oligomer was found to be 90 mass ppm. A mass of nitrogen derived from triethylamine was 0.3 mass ppm. This obtained ingredient will be referred to as “BisB-CF” hereinafter.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: In a procedure substantially like that of Example 1, a mixture of 60 grams of phenol and 8 grams of 2-butanone was reacted in the presence of 1 ml. of mercaptoacetic acid (a catalyst used in place of the octanethiol of Example 1) and 40 ml. of concentrated hydrochloric acid. The Parr bomb and gaseous nitrogen were not used in this procedure. The reaction temperature was about 55° C. The crude reaction product was recrystallized from benzene to yield 5.2 grams of the title compound, which was dried overnight at about 95° C. was reacted in the presence of 1 ml was about 55° C The crude reaction product was recrystallized from benzene
