Process for producing liquid crystal of desired properties by mixing together at least two rigid rodlike helical polymers with narrow molecular weight distributions and different weight-average molecular weights with chiral side chains
Process for producing liquid crystal of desired properties by mixing together at least two rigid rodlike helical polymers with narrow molecular weight distributions and different weight-average molecular weights with chiral side chains
A process to produce a polymer liquid crystalline composition having temperature dependency of desired circular polarization selective reflection wave length property by only mixing two or more kinds of starting materials having different weight-average molecular weight comprising, mixing two or more kinds of rigid rodlike helical polymers with chiral side chains having different weight-average molecular weight synthesized from same molecules and having same repeating unit whose molecular weight distribution defined by the ratio of weight average molecular weight/number average molecular weight is from 1.00 to 1.25, and controlling weight average molecular weight, number average molecular weight and molecular weight distribution by mixing ratio.
