Application

Pentaerythritol tetrakis(3-mercaptopropionate) can be used as a precursor to synthesize:
  • Polymeric degradable networks through thiol-ene click reactions with tri/tetra-acrylates.
  • Thiol-ene-methacrylate composites, which are applicable as dental restorative materials.
  • Network solid polymer electrolytes based on polydimethylsiloxane, for lithium-ion batteries.
It can also be used to functionalize poly(high internal phase emulsions) for removal of heavy metals from water.
