The biomedical poly(ether urethaneurea) Biomer has previously been shown to contain a standard antioxidant and a polymethacrylate additive with surface active properties. In the present communication, the latter additive has been shown to influence the morphology, mechanical properties, and surface chemistry of a poly(ether urethaneurea) with a composition similar to Biomer. It was shown that the in vitro blood compatibility of the poly(ether urethaneurea) was improved and that adsorption of fibrinogen from blood plasma decreased significantly due to the presence of the surface active polymethacrylate additive.
