摘要：

A mixture of PVA (Polyvinyl Alcohol) and CMC (Carboxymethyl Cellulose) polymer solution was prepared and treated for obtaining a polymer carrier for enzyme immobilization. The leakage in water of the mixed solid obtained by the cryogel technique was monitored using UV-Vis spectroscopy for the water solutions and the thermal analysis for the solid polymer. The thermal analysis proved to be a good tool for evidencing the CMC leakage.
