Abstract
Polyesters are prepared from an aromatic dicarboxylic acid or ester-forming derivative thereof with one or more dihydric phenols, which is, or includes, 9: 9-bis(4-hydroxyphenyl)-fluorene. Other phenols which may be used include resorcinol, hydroquinone and those of the formula <FORM:1122201/C3/1> wherein R1 and R2 are alkyl, aryl or fluorinated alkyl groups. The polyesters may be produced by interphase polycondensation, by polycondensation at high temperatures in high-boiling solvents, e.g. a diphenyl/diphenyl ether mixture, chlorinated diphenyl, ditolymethane, nitrobenzene or a -chloronaphthalene, or by low-temperature polycondensation in chlorinated hydrocarbons in the presence of tertiary amine HCl acceptors. In Examples (1) aqueous alkaline fluorene-diphenol is reacted with terephthaloyl chloride in p-xylene, (2), (3) the fluorene-diphenol and in (2) 2: 2-bis (4-hydroxyphenyl)-hexafluoropropane are heated in chlorinated diphenyl with terephthaloyl chloride, and (4) the fluorene-diphenol is condensed with terephthaloyl chloride in dichlorethane i.p.o. triethylamine.
