Description

Application

The Progress in Development of Dental Restorative Materials

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.
