Plasticizer Characterization by TG-IR - PerkinElmer
The TG-IR hyphenation technique has been widely used for the polymer industry, in this case the identification of plasticizer in paint. It combines the strength of TGA and FT-IR analysis and offers a more comprehensive material characterization. The PerkinElmer TG-IR system with the TL 8000 transfer line has

- Does external plasticization reduce TG of a polymer?
- Overall, it was shown that external plasticization was more effective in reducing Tg of a polymer than internal plasticization. Furthermore, this work also demonstrated how Tg of a polymer can be controlled by choosing suitable external and internal plasticizers.
- Do external plasticizers reduce TG?
- It was measured that the three external plasticizers PPH, BC and EEH reduced Tg by similar values of 48–54 K. Integrating these external plasticizers into the polymer as internal plasticizers recovered some of this Tg -loss.
- Can external plasticizers recover a drop in TG?
- In particular, it was demonstrated that a drop in Tg caused by external plasticizers can indeed be recovered by integrating them directly into the polymer. These insights could be used for instance for the design of novel reactive coalescing agents for polymer lattices and coatings [ , , , , , ].
- How is plasticization achieved in polymer morphology?
- Plasticization is achieved by incorporating a plasticizer into polymer matrix, copolymerization, or blending. Among those, adding plasticizer is the most common and simplest way to modify polymer morphology. Plasticizer can lessen the intermolecular forces along the polymer chains. As a result, free volume was increased and T g was lowered.
- What is external plasticization?
- External plasticization where plasticizers are free (a) and internal plasticization, where plasticizing groups are bound to the polymer (b). The effect of small molecules from gases and solvents as well as larger plasticizer compounds on Tg and other properties of the glassy polymer state have been studied with MD simulations.
- What happens when plasticizers are added to polymers?
- When plasticizers added to polymers do not lead to chemical bonding, the process is referred to as external plasticization. Polymer molecules used to achieve internal plasticization are either copolymerized into the polymer structure or reacted with the original polymer.
