Biodegradable Polymeric Materials—Not the Origin but the Chemical Structure Determines Biodegradability

Uwe Witt; Motonori Yamamoto; Ursula Seeliger; Rolf-Joachim Müller; Volker Warzelhan

It is completely plausible that unmodified materials of natural origin, such as the native macromolecules cellulose or starch, are biodegradable. If these materials are modified then degradation may, depending on the degree of modification, be more difficult or even impossible. In the same manner synthesized macromolecules, whether from renewable or petrochemical sources, could be inert or completey biodegradable, depending on their chemical structure.

Biologisch abbaubare Polymerwerkstoffe – nicht die Rohstoffquelle, sondern die chemische Struktur entscheidet über die Abbaubarkeit

Uwe Witt; Motonori Yamamoto; Ursula Seeliger; Rolf-Joachim Müller; Volker Warzelhan

Vollig plausibel ist es, das aus der Natur stammende und unveranderte Stoffe wie die nativen Makromolekule Cellulose und Starke biologisch abbaubar sind. Werden diese Stoffe modifiziert, so kann, abhangig vom Grad dieser Veranderung, der Abbau erschwert bis verhindert werden. Auch synthetisierte Makromolekule, ob auf Basis nachwachsender oder fossiler Rohstoffe, konnen – je nach ihrer chemischen Struktur – inert bis vollstandig biologisch abbaubar sein.
