Types of Step-Growth Polymers: Polyesters01:20

Types of Step-Growth Polymers: Polyesters

2.2K
The introduction of polyesters has brought major development to the textile industry. The wrinkle-free behavior of polyester blends has eliminated the need for starching and ironing clothes.
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...

Olefin Metathesis Polymerization: Acyclic Diene Metathesis (ADMET)

1.9K
Acyclic diene metathesis polymerization or ADMET polymerization involves cross-metathesis of terminal dienes, such as 1,8-nonadiene, to give linear unsaturated polymer and ethylene. As ADMET is a reversible process, the formed ethylene gas must be removed from the reaction mixture to complete the polymerization process.
Similar to cross-metathesis, ADMET also involves the formation of metallacyclobutane intermediate by [2+2] cycloaddition of one of the double bonds of a terminal diene with...

Olefin Metathesis Polymerization: Overview

2.1K
Recently, the development of olefin metathesis polymerization advanced the field of polymer synthesis. Simply put, the reorganization of substituents on their double bonds between two olefins in the presence of a catalyst is known as the olefin metathesis reaction. The use of metathesis reaction for polymer synthesis is called olefin metathesis polymerization.
Ruthenium-based Grubbs catalyst is the most commonly used catalyst for olefin metathesis polymerization. Grubbs catalyst consists...

Area of Science:

  • Polymer Science
  • Biotechnology
  • Materials Science

Background:

  • Non-degradable plastics pose environmental challenges.
  • Reliance on petroleum products creates resource dependency.

Purpose of the Study:

  • To develop an upcycling process for poly (ethylene terephthalate) (PET) plastic waste.
  • To utilize PET waste for producing biodiesel precursors and asphalt modifiers.

Main Methods:

  • A multi-stream fraction strategy was employed to separate PET into soluble and insoluble fractions.
  • Microbial fermentation of the soluble fraction produced biodiesel precursor lipids.
  • The insoluble fraction was used to modify asphalt binder properties.

Main Results:

  • Biodiesel precursor lipids were produced with a notable bioconversion yield.
  • Asphalt binder high-temperature performance improved by 1 performance grade (PG) without compromising low-temperature performance.
  • SEM, FTIR, and 1H NMR analyses confirmed PET incorporation and identified aromatic groups as key to performance enhancement.

Conclusions:

  • The multi-stream fraction approach effectively repurposes PET plastic waste.
  • This method offers a dual solution for sustainable fuel production and enhanced infrastructure resilience.
