Abstract

Optical activity and molecular shape maintain an intimate relationship so that temperature and its ability to cause changes in molecular shape can have a large influence on optical activity. The temperature dependence in moving from glassy to the melt state of the optical activity properties of two polymers, a polyisocyanate with a known important secondary structural influence on its chiral optical properties and a polyketone, is studied in which the presence of regular secondary structure influencing the chiral optical properties was questioned. The optically active polymers may not be entirely amorphous and therefore subject to form birefringence which can interfere with chiral optical measurements of the macromolecular property.
