    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.

  • Patent number: 5117010
    Abstract: The present invention relates to the preparation of di-secondary alcohols comprising the reaction of an alcohol and a diglycidyl ether of a dihydric phenol in the presence of a catalyst of the formula (IV):MX (IV)wherein M is a metal from Groups IB to VIIIB or a metal or metalloid from Groups IIA to VA of the Periodic Chart of Elements or an ammonium ion and X is an anion selected from the group consisting of BF.sub.4.sup.-, PF.sub.6.sup.-, AsF.sub.6.sup.-, SbF.sub.6.sup.-, AlF.sub.4.sup.-, TiF.sub.6.sup.2-, SiF.sub.6.sup.2-, and ZrF.sub.6.sup.2- to produce the di-secondary alcohol, which can then be subjected to glycidylation to produce a glycidyl ether, orthe reaction of an alcohol, glycol or polyol and epichlorohydrin in the presence of the foregoing catalyst, followed by ring closure employing an alkali to produce a mono- or polyglycidyl ether. The monoglycidyl ether can be further reacted with a dihydric phenol to produce a di-secondary alcohol which is then glycidylized to produce a glycidyl ether.
