ABSTRACT:
Hydroxyaromatic oligomers are prepared by (I) reacting (A) an aromatic hydroxyl-containing material such as bisphenol A with (B) a cyanogen halide such as cyanogen bromide in the presence of a base such as triethylamine and (II) co-oligomerizing the cyanate-containing product from (I) with (C) a polymaleimide such as the reaction product of maleic anhydride with methylenedianiline optionally in the presence of (D) a co-oligomerization catalyst such as cobalt naphthenate. These oligomers are useful in the preparation of epoxy resins.
