A specific problem in MS analysis of polymers, which can make it difficult to be performed by normal techniques, is related to the fact that the most common procedure to introduce the sample in the ionization chamber is to take it from the gaseous stream at the end of a gas chromatograph however, the usually high molecular weight and covalent... 

Thermal analysis of polymers was performed on DuPont Model 910 Differential Scanning Calorimeter and a Perkin Elmer Model TQS-2 Thermal Gravimetric Analyzer using a heating rate of 10°C/min. Both systems were interfaced to an Omnitherm Data Station for experiment control, and data acquisition and processing.

Thermal field-flow fractionation was invented by Giddings. The universal applicability of thermal FFF for the analysis of various polymers had been already demonstrated in 1979. Several applications of TFFF to the analysis of polymers and colloidal particles were published (see Refs. for a review) but the contemporary TFFF channels have practically the same dimensions (roughly 50 X 2 X 0.01 cm) as those constructed at the very beginning. Giddings concluded, in 1993, that the miniaturization of the FFF channels could provide only some limited advantages. The experimental studydealt only with the effect of the reduced channel thickness on the performance of TFFF. 

The attenuated reflectance technique presents an excellent example of how radiation at sample surface can enhance signal-to-noise ratio. Details of general optics and reflectance techniques can be found in the classic text (10). This technique is used extensively to determine differences between the structure of polymers in surface and bulk phases. Commercial accessories make these spectroscopic experiments easy to perform, although quantitative analysis of the data remains difficult. Examples of ATR applications include chemical composition analysis of polymers, surface orientation resulting from various processing methods, and chemical or thermal degradation of polymers. For samples such as powders or poorly defined surfaces, the diffuse reflectance technique can be used (11). In addition, the photoacoustic technique has been used to probe surface structure and multilayer structure commonly found in polymer laminates (17). In all these cases, optical effects can complicate analysis of infrared spectra. Nevertheless, these data have proven very useful in analytical applications. 

The conditions for the feasibility of the electrochemical synthesis of PHCs are that the monomer oxidation (or reduction, depending on the route) is accessible via a suitable solvent system and that the produced species reacts to form the polymer preferentially. Electrochemical synthesis has the advantage of producing the material on an electrode on which to perform analysis of the growing process and further experiments by electrochemical and/or spectroscopic techniques. Furthermore, the method allows easy control of the film thickness by the deposition charge.

Dynamic viscosity measurements generally are easier to perform over a wide range of frequencies than are steady shear measurements over a wide range of shear rates, while steady shear viscosity is of more value in the analysis of polymer processing. Thus, the Cox-Merz rule is frequently assumed and t data are used in place of steady shear viscosity data.
