The first four volumes of the series on 'Charged and Reactive
Polymers' have been devoted to polymers in solution (Voh. I and II)
or in gel and membrane forms (Vols. III and IV). In correlation
with charges, other physical or chemical properties of macro
molecules have been considered. Understanding of charge and
hydrophobic effects is equally important for synthetic and
biopolymers or their systems. Optically Active Polymers are related
to problems of the same class, since optical activity is an
inherent property of both natural macromolecules as well as a great
variety of polymers synthesized in the Jast twenty years. Optical
activity is a physical spectral property of chiral matter caused by
asymmetrical configurations, conformations and structures which
have no plane and no center of symmetry and consequently have two
mirror image enantiomeric forms of inverse optical rotation. The
racemic mixture of chiral enantiomers is optically inactive. The
most common form of optical activity was first measured at a
constant wavelength by the angle of rotation of linearly polarized
light. More recently the measurements have been extended to the
entire range of visible and attainable ultraviolet regions where
electronic transitions are observed, giving rise to the ORD
technique (Optical Rotatory Dispersion). The Cotton effects appear
in the region of optically active absorption bands; outside of
these bands the plain curve spectrum is also dependent on all the
electronic transitions of the chromophores."
