Journal ArticleDOI
Oxidation in orthopaedic UHMWPE sterilized by gamma-radiation and ethylene oxide.
Luigi Costa,Maria Paola Luda,L. Trossarelli,E.M. Brach del Prever,Maurizio Crova,Paolo Gallinaro +5 more
TL;DR: The scheme of UHMWPE oxidation due to gamma-sterilization demonstrates the inhomogeneous distribution of reactive species in PEs responsible for the unpredictable performance in vivo.
Journal ArticleDOI
In vivo UHMWPE biodegradation of retrieved prosthesis
Luigi Costa,Maria Paola Luda,L. Trossarelli,E.M. Brach del Prever,Maurizio Crova,Paolo Gallinaro +5 more
TL;DR: Sixty-two ultra high molecular weight polyethylene prosthetic components, sterilised by gamma rays or ethylene oxide, were retrieved after 1-12 years depending on different medical reasons and were studied by FTIR spectroscopy with derivatisation of oxidised species.
Journal ArticleDOI
Stabilisation of ultra-high molecular weight polyethylene with Vitamin E
TL;DR: All the additive-containing samples exhibit better oxidation resistance compared to the virgin material, indicating stabilizing activity of the α-tocopherol derivatives, and hypotheses on the rearrangements of the additive structure include the formation of quinonoid products.
Journal ArticleDOI
Ultra high molecular weight polyethylene—II. Thermal- and photo-oxidation
TL;DR: In this article, the authors used FTIR and derivatisation techniques to study photo-oxidation of ultra high molecular weight polyethylene (UHMWPE) and showed that β-scission prevails in thermo-oxidative conditions whereas Norrish I and Norrish II reactions are the most relevant in photooxidation.
Journal ArticleDOI
Thermal decomposition of fire retardant brominated epoxy resins
TL;DR: In this paper, a mixture of diglycidylethers of bisphenol A (DGBBA)/tetrabromobisphensol A(DGEBTBA) and 4,4′-diaminodiphenylsulphone (DDS) was used to produce a brominated epoxy resin (BER) containing 20% Br.
