The Langmuir-Blodgett (LB) polymerization of two monomers, 2-pentadecyl aniline and 3-hexadecyl pyrrole, is compared. Both monomers reacted to form polymers at air-aqueous 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 LB polymerization experiment where the monomers were pre-oriented in a double compartment trough before chemical polymerization is introduced. The differences in the polymerization behaviour of the two monomers are discussed in terms of their conformation.
