Abstract

Thermally stimulated current spectroscopy has been applied to the characterization of amorphous phases in multiphasic polymers. A preliminary study of the homopolymer has shown that the compensation diagram can be used for defining the structure of an amorphous phase. In synthetic copolymers, the compensation diagram gives phase segregation. Data obtained on a series of latexes are reported as an example. The same methodology can be used in natural copolymers. In the collagen investigated, despite its complex chemical structure, simple behavior of the biphasic copolymers has been found
