Chemical Polymerization and Langmuir-Blodgett Techniques. 2. The Polymerization of Monolayers of 3-Substituted Pyrroles
Abstract
Derivatives of 3-substituted pyrroles were spread at the air-water interface. Stable films could be obtained for pyrroles with side chains containing more than 10 carbons. 3-Hexdecanoyl pyrrole could not be polymerized as a monolayer whereas the alkyl derivatives could be polymerized successfully without having additional monomer in the subphase. It was possible to yield a true two-dimensional polymer monolayer film, without chain overlapping. The monolayers could be transferred onto hydrophobized substrates with transfer ratios being about unity. The polymers formed were soluble in chloroform and THF. Molecular weight averages were obtained by GPC ranged from 3,500 to 6,000 when polymerized on ammonium peroxodisulfate and 5,000 to 15,000 when polymerized on ferric chloride subphase solutions. IH-NMR indicates that the polymerization is highly regular, leading to A constitutionally ordered 2,5 poly(3-alkyl pyrrole).
