چکیده انگلیسی
Poly(propylene carbonate) (PPC) is a biodegradable and partially renewable polymer that is synthesized from CO2. PPC is a suitable alternative to non-degradable polymers and a possible option for effectively recycling CO2. In this study, the properties of PPC are compared with other commercial polymers. It is demonstrated that while the mechanical properties of PPC are comparable to non-degradable polyethylene, its permeability to oxygen and water vapor are remarkably lower. PPC degradation in compost soil is nearly 9% within six months that is comparable with biodegradable polymers such as Eco-Flex. Meanwhile, PPC is chemically stable when exposed to a broad range of simulated media such as low or high pH as negligible mass loss and molecular weight deductions are detected after six months exposure to these media. Therefore, PPC is deemed to be an ideal polymer for food packaging and many other applications such as biomedical devices. The application of PPC can significantly reduce the disposal of non-degradable polymers in landfills and minimize the reliance on fossil fuel based polymers.
