Mannich bases and adducts based on alkyl-dipropylenetriamines, acrylonitrile and ethylene- or propylene-oxide are new, as are also their reaction products with epoxides. Compounds of formula (I) are new, as are also the products obtained by reaction products of (I) with compounds having an average of at least one epoxide group per molecule, the amount of such epoxide reactants being such that 50-80% of the R 2> groups in the reaction products are H. [Image] R 1>1-22C hydrocarbyl; and 50-90% of R 2>H, with the remainder being (i) a phenolic group of formula (II); (ii) -CH 2CH(R c)-OH; or (iii) -CH 2-CH 2-CN; R a and R bH or an aliphatic, cycloaliphatic, aromatic or araliphatic 1-22C group; and R cH or Me.
