Application of ionic liquids as low-volatility plasticizers
Plasticizers are used to improve flexibility, reduce cost and improve the processability of polymers. Ideally, plasticizers would be low in cost, compatible with the host polymer and be easily processed. For extending the lifetime of plasticized materials, the additive must have a low volatility and not leach from the host.

Ionic liquids: New generation stable plasticizers for poly
Fig. 1. Structures of ILs and traditional plasticizers. The effectiveness of these ILs and traditional plasticizers were studied in terms of flexibility, mechanical properties, and high temperature and UV stability they impart to PVC as plasticizers. The leaching and migration tendencies of these plasticizers were also investigated.

Unprecedented exploration of ionic liquids as additives which
Poly(vinyl chloride) (PVC) has been extensively used as a thermoplastic material in the preparation of valuable materials, such as in packaging, health care devices, toys, construction materials, clothes, pipes, etc. Utilization of PVC for such widespread applications is because of its versatile nature, low cost, transparency, flexibility and compatibility with a variety of additives, which
- Are room temperature ionic liquids a plasticizer for poly (vinyl chloride)?
- Room temperature ionic liquids (ILs), based on ammonium, imidazolium and phosphonium cations, were studied as novel plasticizers for poly (vinyl chloride), PVC. All the ILs tested were able to produce flexible PVC.
- Are ionic liquids a good plasticizer for poly (methyl methacrylate)?
- Room temperature ionic liquids (ILs) based on imidazolium salts, were found to be excellent plasticizers for poly (methyl methacrylate), with improved thermal stability, and the ability to reduce glass transition temperatures to near 0 °C.

Ionic liquids in polymer systems: solvents, additives and novel applications. American Chemical Society symposium series, vol. 913. Washington, DC: Am Chem Soc; 2005. p. 103–18.
- Are plasticizers able to produce Flexible PVC?
- All the ILs tested were able to produce flexible PVC. Upon 20 wt% plasticization, some of the ILs lowered the glass transition temperature ( Tg) of PVC more than that done by several traditional plasticizers. They showed good thermodynamic compatibility as well.
- Do ionic liquids change modulus after plasticizer loss due to leaching?
- From this standpoint, many of the ionic liquids showed good behavior, in that the flexibility of the PVC samples changed the least. However, another way of looking at the data is that the plasticizers with high plasticizing efficiency will cause the greatest changes in modulus after plasticizer loss due to leaching.
- Can ILS be used as plasticizers?
- To the best of our knowledge, our work on using ILs in the role of plasticizers has not been reported before, and the results presented here represent the feasibility of using compounds from this class of liquids as plasticizers.
