Polydisperse adducts, RCONR’ (CH 2 CH 2 O) x H, with attractive wetting properties were prepared by oxyethylating aliphatic and aromatic secondary amides to calculated x values of 5 to 20. Moderate wetting profiles were observed with adducts where R and R’ contained 15 to 18 carbon atoms and had short ethylene oxide chains. These products, however, contained unreacted amide and/or ester contaminants. Consequently, the products showed high water solubility, fairly flat surface tension curves and average wetting ability. In the transition of adducts derived from aliphatic amides to those from aromatic amides, unreacted amide concentration decreased and ester contaminant increased.
