Abstract
Products useful as surfactants, corrosion inhibitors, water repellent agents, paint adhesion promoters, etc. are prepared by reacting formaldehyde and a phenol with an alkyl amine containing internal propoxy or propoxy/ethoxy groups to thereby provide a corresponding Mannich condensate having a desired utility. The Mannich condensates may also be reacted with an alkylene oxide feed stock containing ethylene oxide or propylene oxide or 1,2-butylene oxide or a mixture thereof under conventional alkoxylation conditions to thereby provide a corresponding alkoxylated Mannich condensate having a utility which may be the same as or different from the utility of the initial Mannich condensate.
