Special Issue Information

Dear Colleagues,

Polymeric products made from petrochemical polymers are extremely stable in environmental conditions. Following their use, this feature becomes serious problem for the environment. Most of the products made of plastic are stockpiled in landfills, and the decomposition time of such products is often several hundred years. The solution to this problem may be the use of biodegradable polymers derived from renewable materials and which undergo biodegradation.

Biodegradable polymers are distinctly from regular polymers in their material characteristics. Biodegradable polymers, like any other polymer, can be processed using conventional techniques such as injection molding, extrusion, and compression molding. Furthermore, the use of appropriate methods of modification can result in new or improved properties being obtained for the resulting materials. However, the distinct narrow modification and processing window makes them challenging to modify or process.

Continuing technological progress in the modification and processing of biodegradable polymers leads not only to the enhancement of the product quality but also to the reduction of their prices. As a result, biodegradable polymers may be used to produce both common-use articles or packaging materials, as well as for more complex engineering applications.

In this Special Issue, we aim to publish original research and review articles detailing the current trends and technologies for the modification and processing of biodegradable polymers and their composites that are aimed at improving their properties and expanding the possibilities for application.

The results of studies on the uncrosslinked fraction of blends of polylactide and poly(butylene adipate-co-terephthalate) (PLA/PBAT) are presented. The blends were crosslinked by using the electron radiation and triallyl isocyanurate (TAIC) at a concentration of 3 wt %. Two kinds of samples to be investigated were prepared: one contained 80 wt % PLA and the other contained 80 wt % PBAT. Both blends were irradiated with the doses of 10, 40, or 90 kGy. The uncrosslinked fraction was separated from the crosslinked one. When dried, they were subjected to quantitative analysis, Fourier transform infrared spectroscopy (FTIR) measurements, an analysis of variations in the average molecular weight, and the determination of thermal properties. It was found that the electron radiation caused various effects in the studied samples, which depended on the magnitude of the radiation dose and the weight fractions of the components of the particular blends. This was evidenced by the occurrence of the uncrosslinked fractions of different amounts, a different molecular weight distribution, and the different thermal properties of the samples. It was also concluded that the observed effects were caused by the fact that the processes of crosslinking and degradation took place mostly in PLA, while PBAT appeared to be less susceptible to the influence of the electron radiation.
