Abstract
The preparation and homopolymerization of N-acryloyl-10,11-dihydrodibenz[ b, f]azepine is described. The relaxation behaviour is characterized using dielectric relaxation, pulsed n.m.r. and thermally stimulated depolarization (t.s.d.) techniques. In order to assist the assignment of relaxation data to molecular behaviour 5-chloroacetyl and 5-propionyl derivatives of iminobibenzyl were prepared and studied by dielectric relaxation in the matrix-isolated state. Comparison with N-ethyl carbazole under similar conditions revealed the existence of a relaxation in the polymer associated with nitrogen inversion in addition to a relaxation due to the glass transition. The data may be useful in studies relating to the pharmacological activity of the dibenz[ b, f]azepine ring system.
