Monolayer properties of mixtures of poly (n-Butyl methacrylate) and poly (n-Lauryl methacrylate), and their corresponding copolymers

Polylaurylmethacrylate in bidimensional mixtures with low and high molecular weight substances: effect of the chain mobility on mutual miscibility

“…The spreading isotherms of pure PLMA and their behaviour as a function of temperature agreed with those reported in [8] and [9]. At all temperatures considered, a "plateau" was present in the isotherms due to the fact that since the polymer is "fluid" in the bulk phase (at temperatures above its glass point (-65 ~ [12]) and its melting point (-34 ~ [13])), it also forms fluid monomolecular films at the water-air interface.…”

“…PLMA was chosen as the polymer with the "fluidstate" hydrophobic chains because this substance has a fluid monolayer [7] in the whole temperature range tested and because there is the presence, at all the temperatures studied, of a net transition [7][8][9] which is interpreted to be the passage from a fluid monolayer to a tridimensional fluid [7,8].…”
