Article

An analysis is given of the thermal action on an MGA-95 composite porous film cellulose acetate industrial prototype by differential scanning calorimetry. Investigation of an air-dry sample and a water-saturated sample indicates redistribution of the relation in the quantity of perfect crystal structures in crystallites having different values for the enthalpy of melting, which decreases for the low-temperature phase from 6.06 to 0.99 kJ/kg, and for the high-temperature phase, from 1.99 to 1.72 kJ kg. The total melting enthalpy of the endothermic peaks measures from 8.57 to 6.55 kJ/kg, which points to a reduction in the crystallinity of the water-saturated MGA-95 polymer composite film sample.
