ABSTRACT:
Corrosion inhibiting compositions for metals subjected to highly acidic environments may be produced by reacting in a condensation reaction a styrene-acrylic acid copolymer with a polyamine (or combination of polyamines) to produce a polyamidoamine inhibitor. A preferred inhibitor product may be produced by replacing up to 80% of the styrene-acrylic acid copolymer with a member selected from the group consisting of: rosin, C.sub.23 -C.sub.24 modified rosins, C.sub.8 -C.sub.20 fatty acids, C.sub.9-C.sub.22 modified fatty acids, and combinations thereof. These inhibitors exhibit excellent film forming and film persistency characteristics.
