  • What makes a polymer a good plasticizer?
  • It is nowadays established that good plasticization implies secondary bonds, also known as intermolecular forces, with the polymer. The attraction between plasticizer molecules and the polymer must be as strong as the interactions between molecules in the single components to generate an efficient polymer-plasticizer interaction.
  • Can plasticizers reduce material degradation over time?
  • The design of new plasticizers compatible with the polymer at high concentrations, tailored to be effective in lowering the glass transition temperature, and with a low tendency to migration could considerably reduce material degradation over time.
  • Do plasticizers increase polymers' flexibility at room temperature?
  • Disentanglement of CA chains is favored at higher plasticizer content under extensional flow, yielding lower melt strength and higher melt extensibility . These observations confirm that plasticizers increase polymers' flexibility at room temperature and can be used as processing aids.
  • How does a plasticizer work?
  • For a plasticizer to be effective, it must have two structural components. The polar part should bind reversibly with the polymer. The non-polar part adds free volume and contributes shielding effects at other polar sites on the polymer chain. Maintaining a balance between the two parts is critical to prevent compatibility issues.
  • Are plasticizers safe?
  • Plasticizers can enhance compatibility between polymers and various additives or fillers. This results in more homogeneous and stable formulations. Plasticizers such as phthalates can leach out and dissolve into fluids. They can come into contact with skin, raising concerns about potential health effects. 4
  • Does polymer/plasticizer miscibility affect agglomeration of additive droplets?
  • SEM analyses were used to investigate the polymer/plasticizer miscibility, which is a crucial parameter to achieve high plasticizing efficiency, low migration, and thus a long service life. It was observed that phase separation occurs due to agglomeration of additive droplets, when the solubility of a plasticizer in a given polymer is not adequate.
