摘要

The structure of atactic poly(styrene) in films prepared from chloroform solutions was studied by small-angle X-ray scattering and electron microscopy. It was shown that the density fluctuations in films corresponding to dilute poly(styrene) solutions are associated with the aggregates of particles with the radius R_0 close to the hydrodynamic radius of the coil. The value of R_0 in the films decreases with an increase in the poly(styrene) concentration due to the coil entanglement and the blob formation. The coil (its fractal dimension is D = 2) → blob (D = 3) transition leads to an increase in the density and glass transition temperature of films, which is caused by enhancing interchain and intrachain interactions of segments in the solid state of atactic poly(styrene).
