Polymeric materials such as: poly(n-octadecyl methacrylate), poly(n-octadecyl methacrylate-co-N-p-nitrophenylmaleimide) and poly(n-octadecyl methacrylate-co-N-p-nitrophrnylacrylamide) were synthesized to investigate their ability for monolayer film formation and deposition. It was found that polymerization of n-octadecyl methacrylateee yielded the material with improved ability of film formation as compared with the monomer, and the surface pressure-area isotherm showed a distinct solid film phase formation with a high value of film collapse pressure of ca. 56 mN/m. The incorporation of a co-monomer resulted in a shift of the surface pressure isotherm towards higher area values, still with a distinct solid film phase region and high film collapse pressure. The thickness of the poly(n-octadecyl methacrylate) film deposited onto a solid subphase was ca. 3 nm per monolayer (as determined by surface plasmon resonance) and this value corresponded to the lenght of the monomer molecule.
