Notes:
Infrared spectra indicate that carboxyl-substituted acrylic copolymers react appreci8bly with a butylated melamine-formaldehyde resin when heated at 120°C. for 30 min., but under these conditions acid catalysis is needed before epoxy- or amido-substituted copolymers will crosslink with the melamine-formaldehyde resin. Two methods have been used to synthesize hydroxyl-substituted acrylic copolymers. First, a glycidyl methacrylate copolymer was reacted with diethplamine. Second, an acrylic acid copolymer was heated under reflux with butylene oxide in the presence of a basic catalyst. This second method was used to esterify a vinyl toluene-acrylic acid-acrylamide copolymer which was subsequently treated with paraformaldehyde. The resulting hydroxy-methylolamido copolymer intercondensed when heated at 120°C. for 30 min., somewhat as did the hydroxy copolymer with melamine-formaldehyde resin blends.
