Influence of the Multiple Injection Moulding and Composting Time on the Properties of Selected Packaging and Furan-Based Polyesters

Abstract In recent years, there has been a trend toward replacing petrochemical raw materials with so-called “bio” plastics, i.e. plastics from renewable sources. Herein, the susceptibility of degradation in compost heap three types packaging polyesters, by means PET and biobased PEF PLA, other thermoplastic polyesters more methylene groups (three six) bio—(PTF PHF, respectively) petrochemically-based (PTT PHT, studied. Two series polymer based on ethylene, propylene, hexamethylene glycols two diesters (dimethyl terephthalate dimethyl 2,5-furandicarboxylate) were thus obtained compared “double green” PLA. Moreover, assessment influence subsequent processing cycle (injection moulding) utilitarian properties these materials, constitutes analogy to recycling cycle. The was assessed context changes structure (analyzed FTIR DSC), intrinsic viscosity, mechanical performance. addition, chromatographic analysis solutions analyzed samples methanol carried out order determine whether what low-molecular compounds released polyesters. It shown that furan-based have great potential replace terephthalate-based
