ABSTRACT:
A method for the preparation of soluble, fusible, aminomethyl diaryl compound resins in the absence of halomethylation or halomethylated materials, which method comprises (a) refluxing a mixture of diaryl compound, an aldehyde, a saturated monocarboxylic acid, and a small amount of a strong acid catalyst to form an aldehyde-diaryl resin, (b) stripping off excess monocarboxylic acid under vacuum, and then (c) adding at least about 1 mole of a primary or secondary amine containing at least one additional nontertiary amino group per reactive group on the aldehyde-diaryl resin.
