Two extreme types of polyanions can be distinguished. In the first, the main chain is flexible and can assume a large number of different conformations so that the overall shape of the ion depends on the solvent. In some solvents (called bad ), they are rolled up to form a relatively rigid random coil , while in others ( good ) the coil is more or less expanded. This type includes most synthetic polyelectrolytes such as the following acids ... [Pg.85]

Further details of the theory and application of Raman spectroscopy in polymer studies can be found elsewhere (1. 9). However, vibrational frequencies of functional groups in polymers can be characterized from the spacing of the Raman lines and thus information complementary to IR absorption spectroscopy can be obtained. In addition, since visible radiation is used the technique can be applied to aqueous media in contrast to IR spectroscopy, allowing studies of synthetic polyelectrolytes and biopolymers to be undertaken. Conformation and crystallinity of polymers have also been shown to influence the Raman spectra Q.) while the possibility of studying scattering from small sample volumes in the focussed laser beam (-100 pm diameter) can provide information on localized changes in chemical structure. [Pg.36]

B. by promoting interparticle attraction. These materials are styrene copolymers with carboxyl groups, synthetic polyelectrolytes and natural gums. [Pg.319]
