摘要：
Poly(3-hydroxybutyrate) membranes, obtained by casting of a chloroform solution, were studied by method of wide- angle X-ray scattering (WAXS). The membranes typically have an axial texture of the crystalline phase, with the polymer chain oriented predominantly perpendicularly to the membrane plane. Intensity of The (020) reflection, which served as a quantitative characteristic of the degree of texture perfection, was measured for various inclination angles of the sample. It is concluded thar membranes contain oriented (66%) and unoriented crystallite fractions. The values of the orientation function are presented.
