According to this theory, the free volume of a glassy polymer at T g is 2.5% of the total volume. The WLF equation is one of the most successful theories of free volume. Principally, the free volume in the polymer structure comes from three main motions: the motion of chain ends,

Plasticizers also markedly affect the melting behavior of polymers. During the melting process, plasticizers are expelled from crystalline regions, accumulating in the amorphous areas. This expulsion broadens the melting

Good compatibility requires matching polar plasticizers with polymers that have polar groups. The distance of the polymer's polar groups also influences the plasticizer polarity

In comparison to their linear counterparts, hyperbranched plasticizers exhibit high terminal functional group concentrations and, therefore, are able to increase free volume in polymer matrices. On the other hand, a high molecular weight

Plasticizers are generally nonvolatile, high boiling, Then, 12 mL of polymer–plasticizer solution was cast into a level Teflon Petri dish and dried at 50°C, for approximately 4.5 h, until the loss

Virgin biopolymers are often brittle and therefore need the addition of plasticizers to obtain the required mechanical properties for practical applications, for example, in bags and disposable kitchen items. In this article,

Antiplasticization of glassy polymers, arising from the addition of small amounts of plasticizer, was examined to highlight the developments that have taken place over the last few decades, aiming to fill gaps of knowledge in

The addition of a plasticizer to PVC can improve its workability, decrease its processing temperature, and achieve the desired toughness [9,10,11,12]. Plasticizer is one of
