Abstract

Monolayers of vinyl stearate and bulk poly(vinyl stearate) were maintained at constant pressures of 15 dyn/cm and spread on subphases of pH ranging from 2 to 12 in order to determine the extent of ester hydrolysis under these experimental conditions. Monomer films exposed to basic subphases for 6 h appeared to undergo base hydrolysis, while those spread on acidic subphases for the identical length of time underwent cationic polymerization as well as acid hydrolysis of the ester. Hydrolysis of polymer films did not appear to occur over the entire surface pressure and pH range employed in this study. The resistance of the polymer film to chemical attack was attributed to the steric hindrance of the polymer backbone to attacking ions. The relation of chemical resistivity of the monolayer at the gas—water interface to device fabrication was also discussed.
