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 essential to give certain polymers the specific properties they need for use in specialized medical devices and components. Because they often require sophisticated purification processes and equipment, PTG is highly qualified to research, develop, and produce oligomers.
Some successful PTG-specific oligomer projects include silicone hydrogel oligomers and hydrophilic biocompatible polyethylene glycol oligomers.
