Types of Step-Growth Polymers: Polyesters

Types of Step-Growth Polymers: Polyesters

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: Ring-Opening Metathesis Polymerization (ROMP)

Olefin Metathesis Polymerization: Ring-Opening Metathesis Polymerization (ROMP)

Ring-opening metathesis polymerization or ROMP involves strained cycloalkenes as starting materials. The mechanism of ROMP proceeds by reacting cycloalkene with Grubbs catalyst to give metallacyclobutane intermediate which undergoes a ring-opening reaction to form new carbene. The new carbene reacts with another molecule of cycloalkene. Repetition of these steps leads to the formation of an unsaturated open-chain polymer product. All these steps are reversible, however, relieving the ring...

Supercritical Fluid Chromatography

Supercritical Fluid Chromatography

Supercritical fluid chromatography (SFC) provides a beneficial substitute for gas chromatography (GC) and liquid chromatography (LC) for certain samples because it merges the top attributes of both techniques. SFC allows the separation and analysis of compounds that GC or LC does not easily manage. These compounds are traditionally nonvolatile or thermally unstable, making GC unsuitable and lacking functional groups required for HPLC analysis.
SFC utilizes a supercritical fluid mobile phase,...

Background:

Plasticizers in poly(vinyl chloride) (PVC) hinder effective recycling.
Developing sustainable methods for plasticizer removal is crucial for circular economy initiatives.

Purpose of the Study:

To investigate the efficiency of supercritical carbon dioxide (scCO2) extraction for removing plasticizers from PVC.
To assess the impact of scCO2 extraction on the purity and properties of recycled PVC.

Main Methods:

Extraction experiments using supercritical carbon dioxide at pressures from 100 to 500 bar and temperatures from 75 to 110 °C.
Characterization of extracted PVC using gel permeation chromatography, rheology, tensile testing, and scanning electron microscopy.
Process modeling using the Sovová model to describe the extraction kinetics.

Main Results:

Achieved over 98% extraction efficiency for bis(2-ethylhexyl) phthalate (DOP) from PVC.
Produced PVC samples with over 99.5% purity.
The Sovová model accurately described the supercritical extraction process.

Conclusions:

Supercritical carbon dioxide is a highly effective and efficient method for removing plasticizers from PVC.
The scCO2 extraction process maintains the integrity of PVC's physical and molecular properties, making it suitable for recycling.
This technology offers a promising route for enhancing the recyclability of PVC and promoting a circular economy.
