Plasticizers are among the most widely used additives in the industry, with a market estimated at $17 million, representing over 60 % of the additives market . They are defined by IUPAC as « a material incorporated in a polymer to increase the polymer's workability, flexibility or extensibility » . They are essential for enhancing polymer flexibility and mobility, improving processability , with a great reduction of the glass transition temperature (Tg) of the matrix. Plasticizers also decrease the stiffness of the matrix as represented by Young's modulus (E) and increase the elongation at break (εmax) . They modify intermolecular forces and polymer crystallinity, by increasing the free volume and the chains mobility . They thus make it possible to adjust the thermomechanical properties of a material for a specific application or process. For example, some thermoplastics are too rigid and brittle to be easily shaped by conventional thermomechanical processes. Thanks to plasticizers, these polymers could be shaped more easily, acquiring new properties, opening up new fields of application.
