Alkylated and/or aralkylated polyhydroxy aromatic compounds and processes for their preparation and use

摘要

Alkylated and/or aralkylated polyhydroxy aromatic compounds prepared by reaction of a polyhydroxy aromatic compound (A) with an alkylene compound (B) at elevated temperature with the addition of a mixture (C) of oxalic acid and boric acid in a molar ratio of from 1:5 to 1:0, are useful, for example, as starting materials for the preparation of condensation polymers.
