“…However, Vasileiou et al reported that the presence of fumed silica particles has a negative effect on the degradation level of PESu since it reduces macromolecular chain mobility. A reduced hydrolysis rate was also found in PPSeb/MMT nanocomposite, which is in agreement with some reported findings in literature [17,27,28]. Enzymatic degradation of polyesters can be affected by several factors, having to do with the chemical structure, the type and amount of filler, the solidstate of the degraded specimen.…”

“…This effect is due to the improvement in water barrier properties of the 535 nano.biocomposites, which could hinder the water diffusion through the bulk and consequently 536 decrease the hydrolysis rate (Lee, Park, Lim, Kang, Li & Cho, 2002). 537 out to evaluate the effect of the addition of silver nanoparticles and s-CNC nanocrystals on the 539 disintegrability properties of the PLA matrix.…”

26Ternary nano-biocomposite films based on poly(lactic acid) (PLA) with modified cellulose 27 nanocrystals (s-CNC) and synthesized silver nanoparticles (Ag) have been prepared and 28 characterized. The functionalization of the CNC surface with an acid phosphate ester of ethoxylated 29 nonylphenol favoured its dispersion in the PLA matrix. The positive effects of the addition of 30 cellulose and silver on the PLA barrier properties were confirmed by reductions in the water 31 permeability (WVP) and oxygen transmission rate (OTR) of the films tested. The migration level of 32 all nano-biocomposites in contact with food simulants were below the permitted limits in both non-33 polar and polar simulants. PLA nano-biocomposites showed a significant antibacterial activity 34 influenced by the Ag content, while composting tests showed that the materials were visibly 35 disintegrated after 15 days with the ternary systems showing the highest rate of disintegration under 36 composting conditions. 37 38

“…Within the class of polyesters, aliphatic polyesters are considered important biodegradable polymers [1]. The properties of commercialized biodegradable polymeric materials, such as melting point or mechanical properties, are usually rather poor and below the requirements for many applications.…”

A comprehensive study using liquid chromatography electrospray ionization multistage mass spectrometry (LC-ESI MS n ) was performed to get detailed structural information on poly(butylene adipate-co-butylene terephthalate) co-polyester and its product of partial degradation. LC-MS and LC-MS n identified the existence of cyclic structures in the original samples that disappear completely during the degradation. The occurrence of methanol transesterification in the degradation process was confirmed. MS 2 on the first 13 C isotope peak helped to determine the elemental composition of the fragments and facilitated end group determination. The method can be used to provide an alternative for high mass accuracy MS 2 experiments. Sequence information was also revealed for certain copolymeric structures.
