ABSTRACT:
Ethylene and propylene oxide adducts of rosin amides are novel compositions of matter useful for the protection of metal from corrosiion and useful as surface active agents for the emulsification and demulsification of multi-phase liquid systems. These compounds are prepared by the addition of ethylene or propylene oxide (or mixture of the two) under moderate pressures and temperatures, with or without catalysts, to the starting rosin amides.
