PROPERTIES OF POLYCYANOACRYLATE MONOLAYER S

Surface-active properties of polycyanoacrylate monolayers at the air-w ater interface were investigated. Monolayers of polycyanoacrylates wit h the side chains comprising six to ten carbon atoms were found to be stable at the water surface and could be transferred to a hydrophilic or a hydrophobic surface by the Langmuir-Blodgett method. Water temper ature during the formation of polycyanoacrylate monolayer was maintain ed at 16 - 18-degrees-C. Molecular masses of polycyanoacrylates With C 5, C-7, and C-10 side chains formed at the water surface were found to be 1.5 x 10(5); 0.4 x 10(5), and 2.2 x 10(5), respectively.
