Abstract:

The Langmuir-Blodgett polymerization of two monomers, 2-pentadecyl aniline and 3-hexadecyl pyrrole, is compared. Both monomers reacted to form polymers at airaqueous interfaces. The aniline monomer showed autoacceleration upon polymerization and polymerized much faster as the applied surface pressure increased. The pyrrole monomer polymerized faster than the aniline, but showed little dependence on applied surface pressure. A new Langmuir-Blodgett polymerization experiment where the monomers were preoriented in a double compartment trough before chemical polymerization is introduced. The differences in the polymerization behavior of the two monomers is discussed in terms of their conformation.
