Synthetic resin

In order to undergo curing, resins typically contain reactive end groups,[2] such as acrylates or epoxides.

The classic variety is epoxy resin, manufactured through polymerization-polyaddition or polycondensation reactions, used as a thermoset polymer for adhesives and composites.

Certain ion-exchange resins are also used pharmaceutically as bile acid sequestrants, mainly as hypolipidemic agents, although they may be used for purposes other than lowering cholesterol.

[5] Silicone resins are silicone-based polymers that exhibit various useful properties like weatherability (durability), dielectricity, water repellency, thermal stability, and chemical inertness.

Issues of interest include the effects of unconsumed monomers, oligomers, and solvent carriers.

Dental restorative materials based on bis-GMA-containing resins[7] can break down into or be contaminated with the related compound bisphenol A, a potential endocrine disruptor.
