Abstract
The invention relates to carbonate-linked surface modifying macromolecules and admixtures thereof. The admixtures can be used in industrial and medical applications where enhanced surface properties are desirable (e.g., surface properties reducing or preventing biofouling, immobilization of biomolecules, or denaturation of certain biomolecules).
