摘要：
Dielectric relaxation in solutions of aromatic polyesters containing silarene fragments was studied. These polymers show three regions of dielectric relaxation which reflect three types of molecular motions. Analysis of dipole polarization relaxation reveals that an isolated macromolecule of aromatic polyester containing silarene fragments shows relatively high intramolecular lability. No aggregation phenomena, which are generally characteristic of LC polymers, are observed in solutions of these polymers.
