Process for producing liquid crystal of desired properties by mixing together at least two still rod-shaped polymers of narrow molecular weight distributions and different weight-average molecular weights having chiral side chain groups |
摘要 |
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.
