Molecular engineering of manipulated alginate-based polyurethanes

- Novel chemically-bonded alginates into the polyurethane structures were synthesized.
- All alginate based polyurethanes were soluble in common aprotic organic solvents.
- Alginate was used as a chain extender in polyurethane structure for the first time.
- All alginate based polyurethanes were synthesized under catalyst-free conditions.
- Properties of samples were extremely dependent on ionic nature of polyurethanes.
