The optical properties of bottles are a matter of crystallinity affected by nucle-ation, depending on the content and size of light-scattering polymer solids. The purity of the raw materials and the cleanness of the reactors are prerequisites for satisfactory quality. Bottle polymer should display as little contaminations as possible. The detection of impurities is carried out by the same methods as mentioned above. Thorough filtration of the polymer is therefore mandatory. It should... 

The value of c, is measured using a concentration-sensitive detector, which is usually a differential refractometer. As in the case of light scattering, polymer concentration during an SEC experiment is considered to be close to infinite dilution thus, extrapolation to zero concentration is not required. Providing that universal calibration is valid for a given SEC system, data of the polymer at each elution volume increment Mi can be determined ...

This chapter is the narrowest in scope of any chapter in this book. In it we discuss a single experimental procedure and its interpretation. It is appropriate to examine light scattering in considerable detail, since the theory underlying this method is relatively unfamiliar to students and the interpretation yields information concerning a variety of polymer parameters. 

The scattering of visible light by polymer solutions is our primary interest in this chapter. However, since is a function of the ratio R/X, as we saw in the last section, the phenomena we discuss are applicable to the entire range of the electromagnetic spectrum. Accordingly, a general review of the properties of this radiation and its interactions with matter is worthwhile before a specific consideration of scattering. 

Next let us consider the light scattered by liquids of low molecular weight compounds. We are actually not directly interested in this quantity per se, but in scattering by solutions-polymer solutions eventually, but for now solutions of small solute molecules. The solvent in such a solution does scatter, but, in practice, the intensity of light scattered by pure solvent is measured and subtracted as a blank correction from the scattering by the solution.
