Abstract
The disclosed technology provides thermoplastic polyurethane compositions having antimicrobial properties while still maintaining good physical properties and good non-fouling properties, methods of making the same, and articles, including medical devices, made from such compositions. The disclosed technology includes a process of making an antimicrobial polymer composition, where the process includes mixing an antimicrobial additive into a base polymer and further includes mixing in a non-fouling additive, where the antimicrobial additive is chemically held in the composition and the antimicrobial and non-fouling additives do not negatively impact each other's effectiveness.
