aIn this work, poly(lactic acid) and poly(butylene adipate-co-terephthalate) (PLA/PBAT 50/50) were meltblended in the presence of 4,4 0 -methylene diphenyl diisocyanate (MDI) which acted as a reactive chain extender. The mechanical properties, phase morphology, thermal behavior and crystalline structure of the blends were investigated. Fourier transform infrared measurements revealed that some remarkable chemical interaction had taken place between the two polymers and MDI. Upon increasing the content of MDI, the blends showed increased tensile strength and elongation at break. With the addition of 0-2 wt% MDI, the impact strength of PLA/PBAT-MDI blends increased from 7.0 kJ m À2 to 70.0 kJ m À2. A large shift towards each other in terms of the glass transition temperature was observed by DMA and DSC analysis. SEM micrographs showed not only a reduction in the PBAT phase size but also a significant increase in interfacial adhesion between the PLA and PBAT phases with increasing of MDI. Furthermore, the toughening mechanism of the oriented samples was confirmed by wide-angle X-ray diffraction (WAXD) and small-angle X-ray scattering (SAXS) images; it was possible for the smaller crystallites of blends to form during the course of chain extension.

“…Advances in the area of packaging are related to efforts to improve the quality of packaged goods, and extend their "best before" date while increasing the packaging's usability and marketing functions. In order to ensure the quality of packaged goods, not only that of food products, it is necessary to provide appropriate barrier properties against gases and water vapour [1][2][3][4].…”

The Influence of Recycled Single Polymer Polyester Composites on Gas Permeability

Single polymer polyester composites were recycled by compression moulding and extrusion. The recycled products were formed into films of 5 cm 2 surface area and about 250 µm thick. The paper has presented the influence of recycled materials on the permeability of gases (O2, CO2, N2) and water vapour through the walls of the produced films. The influence of processing on the gas barrier of thin films was also determined. The results obtained were compared with the properties of commercial materials.
