  The surface behaviors of monolayers of the poly(itaconate) derivatives, poly(dibenzyl itaconate) (PDBzI) and poly(monobenzyl itaconate) (PMBzI), at the air-water interface were investigated at 298 K on an aqueous subphase at pH 5.7 and 3.0. The monolayer characteristics of PDBzI and PMBzI were studied and compared in terms of surface pressure-area (-A) isotherms, surface compressional modulus-surface pressure (Cs-1-π) curves, static elasticity-surface concentration curves (-), hysteresis phenomena and phase images observed with a Brewster angle microscope (BAM.). The results showed that PMBzI and PDBzI gave rise to stable monolayers and that the isotherms presented pseudoplateau regions at different surface pressure values independent of pH. The PMBzl pseudoplateau region may because a change in the lateral packing of the chains. The PDBzl pseudoplateau region is attributed to a ph.. Read More»
