摘要：

It was shown that the optical and dielectric properties of polyimides (PIs) are affected by both the presence of an alicyclic fragment and the non-coplanarity of the structural elements of the polymer chain. The combination of these factors contributed to an increase of the transparency of the PIs in the optical range and a decrease of the dielectric constant. It was determined that the introduction of 20 mol.% adamantane-containing diamine into the PI structure contributed to its more complete amorphization and increased its transparency.
