Selected biodegradable polymers - preparation, properties, applications

Applications of Printed Materials

“…The main advantage of these materials is their biodegradability which, depending on the processing condition, lasts from several months to several years (Gołębiewski, Gibas, & Malinowski, 2008;Katiyar et al, 2014;Marsh & Bugusu, 2007). They may be made from not only renewable raw materials such as maize, potatoes, sugar cane, sugar beet, and biomass, but also from petrochemical materials, like in the case of traditional polymers.…”

Renewable raw materials as an alternative to receiving biodegradable materials

“…Ich wytrzymałość mechaniczna i trwałość były zbyt niskie i dlatego do skrobi domieszkowano kilka procent naturalnych włókien [21] i polimerów syntetycznych [22]. Z łączenia skrobi z syntetycznymi, lecz biodegradowalnymi polimerami, jak różne poliestry, otrzymano powoli biodegradujące się polimery typu Mater-Bi [23,24]. Dużą popularność zyskały polimery biodegradowalne otrzymywane bez użycia skrobi.…”

Poly(ethylene glycol) functionalized by polycondensing procedure with poly(succinimide)

“…The interest in development of biodegradable and biocompatible polymers, as for example poly(a-hydroxyl acid)s and poly(a-amino acid)s for biomedical and pharmaceutical applications has considerable increased [1]. Currently there are few synthetic and natural polymeric materials which can be used for controlled delivery of drugs, including peptide and protein drugs, because of strict regulatory compliance requirements, such as biocompatibility, clearly defined degradation pathway and safety of the degradation products [2][3][4]. Among these, the most commonly used hydrophilic blocks comprise of poly(ethylene glycol) (PEG) with the monomer subunit -CH 2 -CH 2 -O-, the end groups depending on the synthesis procedure most often being hydroxyl or methoxy groups.…”
