Abstract
The influence of surfactant / polymer (polyethylene glycol, PEG, mel. wt. = 400) mixtures upon the acidic hydrolysis of two N-substituted hydroxamic a cids, i.e., R(CO). N(OH)R': R = C6H5, R' = C6H5; 4-CH3C6H4 has been studied using cationic (CTAB, TTAB and CPC) and nonionic (TX-100 and Brij-35) surf actants. An inhibitory effect was observed, The results have been explained by Portnoy - Menger model. The critical aggregation concentration and poly mer saturation point-of the corresponding systems have also been measured w ith the conductivity and surface tension methods.
