Abstract: Linear aromatic polymeric species, particularly oligomers and polymers are produced under mild conditions in good yield by reacting an at least binuclear aromatic compound with an alkylidene bisphenol in the presence of a non C-alkylatable hydroxy substituted aromatic compound effective to stabilize a generated carbonium ion intermediate; the alkylidene bisphenol may be formed in situ from a ketone or aldehyde in the presence of a catalytic amount of a hydroxy substituted aromatic compound effective to generate a carbonium ion with the ketone or aldehyde; carrying out the reaction under reduced pressure, particularly high vacuum permits direct production of high polymers; the oligomers are useful in the manufacture of high molecular weight engineering or industrial plastics; the polymers may be used directly as such plastics.
