Alkyl phenol oxyethylated ester

Consider the properties of reactive surface-active (RS) substances (alkyl phenol oxyethylated ester (OP-10), dodecyl nitrile (DDN)) and of chemically indifferent smface-active substances (IS) like the ohgo-amidoamines L-18, L-19, L-20 capable of reacting with such oligomeric solvents as the ED-20 and DEG-1 epoxy resins and polyoxypropylene-triol (POPT) of molecular weight 750. These oligomers are imasso-ciated low-polarity liquids, as confirmed by the data of Table 2.1.
