  • How to select solid-state plasticizer?
  • The selection of solid-state plasticizer should include miscibility of plasticizer in polymer as well as API and its effect on T g and η 0 of the final system. It can be summarized that when components are miscible, different techniques will lead to the consistent plasticization effect prediction.
  • Why are plasticizers added to ca?
  • Plasticizers are added to CA to increase workability, prevent degradation under processing conditions and ensure thermo-mechanical properties suitable for the intended final application. Moreover, inexpensive and non-toxic solvents enable its processing into fibers, films, and solid blocks.
  • Are LA-based plasticizers a ketal-diester?
  • (39) Recently, Xuan and co-workers developed LA-based plasticizers to tailor poly (lactic acid) (PLA) properties, varying both the side chains and the central structure of the plasticizer. (40,41) Also, our group, in the latest years, has proposed an LA-based ketal–diester synthesized by a selective protecting-group-free route as plasticizers.
  • Which plasticizers are the most important commercially?
  • This is why external plasticizers are the most important commercially. External plasticizers can be monomeric or polymeric. Examples for polymeric plasticizers are EVA, CPE, NBR and terpolymers or polyesters mainly based on adipic acid, diols and mono alcohols.
  • What are low molecular weight plasticizers?
  • Low molecular weight plasticizers are added before or during the processing to reduce the melt processing temperature. However, these low molecular weight plasticizers may have some drawbacks, such as volatility, high water solubility, and insufficient compatibility with CA.
  • What plasticizers are used in hot-melt extruded systems?
  • Although commonly used pharmaceutical plasticizers such as triacetin, 4 citrate esters, 2, 5 and lower molecular weight polyethylene glycols 2, 3, 4 have been investigated in hot-melt extruded systems, almost all of them are liquid.
