Zusammenfassung

This chapter discusses the structure and physical properties of polymers. Polymers can exist in four physical states—the crystalline and three amorphous states (glassy, rubbery, and viscous flow). Polymers that exist in the glassy or crystalline state are sometimes called rigid polymers. Each state has its own complex of mechanical properties and its own area of technical application. The physical state of a polymer is most often determined by studying its mechanical properties, for example, its compliance. Flexibility is the basic property of chain molecules. A polymer molecule has a transverse dimension of several angstroms and a length of several thousand angstroms, which may form fiber 10 microns in diameter and several millimeters in length.
