Abstract

This chapter discusses the applications of IR spectroscopy to polymers. To identify the chemical nature of the polymer or to determine its composition, IR is a highly useful specific tool. For quantitative analysis of microstructure, stereoregularity, branching, or crosslinking, in many cases, IR analysis is the simplest and most sensitive method. It is a popular tool in the arsenal of the polymer scientist. With the help of IR spectroscopy, the quality of the instrumentation is improving, and the cost is decreasing so that quality instrumentation is available to laboratories of all sizes. IR instrumentation is moving into the quality control laboratory because of its sensitivity to small differences in samples. It is also being used in chemical plants as a process-monitoring device because of its capability of continuously monitoring a large variety of structural aspects in a process stream.
