Oligomers are short chain polymers used as intermediates for further polymerization or other reactions. They are often not commercially available because of the difficulty or expense required to produce them in large quantities with high purity. However, oligomers are necessary to create polymers with specific functionality.

Ensuring precise functionality and molecular weight are often essential and give polymers the specific properties they need for use in specialized medical devices and components. Because they often require sophisticated purification processes and equipment, PTG's staff and facilities are an ideal match for projects of this type.

Some PTG oligomer products include silicone hydrogel oligomers and hydrophilic biocompatible polyethylene glycol oligomers.
