Abstract

The conformation of block cooligomers that contain a block of eight 2,6,7,10,11-pentapentyloxy-3-(3-acryloylpropyloxy)triphenylene units and a poly(tert-butyl acrylate) block with a length varying from 6 to 300 monomer units was calculated by means of molecular dynamics with the DREIDING force field. The influence of the length of the flexible-chain block of the amorphous polymer on the conformation and structure of the block cooligomer at the level of a single macromolecule was revealed. A tendency toward the screening of the short mesogen-containing block by the flexible-chain polymer block with an increase in its length was demonstrated.
