Synthetic polymer chemists face a plastic waste crisis. Focusing on chemical recycling and life cycle assessments is crucial for a sustainable, closed-loop plastic economy.
Area of Science:
- Polymer Chemistry
- Environmental Science
- Materials Science
Background:
- The widespread use of synthetic polymers has led to a global plastic waste crisis, impacting environmental and public health.
- Current research on sustainable polymers predominantly focuses on biomass-derived feedstocks, neglecting end-of-life considerations.
Purpose of the Study:
- To assess the current research landscape of sustainable polymers.
- To advocate for a shift in focus towards polymer end-of-life management and chemical recycling.
Main Methods:
- Comprehensive literature survey on "sustainable polymers" research.
- Analysis of research trends concerning polymer feedstocks versus end-of-life fates.
Main Results:
- An increasing trend in publications on sustainable polymers, with a strong emphasis on biomass-derived materials.
- A relative scarcity of research addressing the end-of-life management of synthetic polymers.
Conclusions:
- The synthetic polymer community needs to broaden its scope beyond feedstock innovation to include end-of-life solutions.
- Implementing chemical recycling and life cycle assessments is vital for developing a sustainable, closed-loop plastic economy.

Types of Step-Growth Polymers: Polyesters
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the...
Molecular Weight of Step-Growth Polymers
As the step-growth polymerization involves step-wise condensation of monomers, the molecular weight also builds up eventually. Consequently, high molecular weight polymers are obtained at the late stages of the polymerization, where 99% of monomers have been consumed.
