Studies of the solubility of chitin from North Sea shrimp shells in aqueous NaOH solutions with urea and thiourea additives showed that chitin was totally dissolved in aqueous NaOH (10%) + urea (5%) + thiourea (5%). A thermally reversible gel formed if the solutions were stored at room temperature. The structures of chitin films obtained from the solutions were studied using IR spectroscopy and x-ray diffraction.
