In the presented paper, two basic strategies that can be used in processes of chemical recycling polyester material were described. The first them involves increasing molar mass recycled materials solid-state polycondensation (SSP) process and/or joining their chains with various types substances easily reacting end groups polyesters (so-called extending agents). essence second strategy is degradation under influence protogenic agents (such as water, alcohols, glycols and amines) to obtain low-molecular products or oligomers raw synthesis many classes polymers. methods are already PET [poly(ethylene terephthalate)] possibility extension other both shown.
