Abstract
A supramolecular polymer blend includes a thermoplastic elastomer functionalized with at least one bis-urea moiety and a functional component which is functionalized with at least one bis-urea moiety which is present in an amount of 0.5-40 wt % based on the total mass of the polymer blend. The functional component is selected from polyalkylene glycol, betaine, polysaccharide, zwitterion, polyol or taurine and derivatives thereof. Implants including the polymer blend and a process to manufacture the implants are also provided.
