Polymericmaterials, both"inert"anddegradable,
constantlyinteractwiththe surroundings. Because of this interaction
changes take place in the polymer matrix and small molecules are
released to the environment. Reliable me- ods for testing
biodegradability and environmental interaction of renewable
resources and biodegradable polymers are required to answer the
rema- ing questions concerning the environmental impact of these
future materials.
Inthecaseofdegradablepolymersmultiplefactorsaffectthedegradation
process and small changes in the chemical structure or product
formulation may change the susceptibility to degradation or cause
different degradation product patterns, rendering the product less
environmentally adaptable. - velopment of sustainable polymeric
materials also demands the development of more migration-resistant
polymer additives. Chromatographic techniques especially
gaschromatographyandliquidchromatographypreferentially c- pled to
mass spectrometric detection are ideal tools for studying these low
molecular weight compounds and polymer-environment interactions. In
the ?rst chapter of this volume chromatographic ?ngerprinting and -
dicator product concepts are presented as tools for evaluating
polymeric - terials. These concepts have great potential in
evaluation of degradation state andlife-time/service-life
ofpolymericmaterials, evaluation ofanti-oxidant or pro-oxidant
systems, degradation mechanism and processing parameters as
