ABSTRACT
The results discussed so far confirm the important role of surface phenomena in effects of different type on the polymer systems. These effect are associated, firstly, with the fact that they cause changes in the area of the interface of the polymer and the associated transport of the material from the bulk to the surface and vice versa. It is evident that these processes should be controlled by surface-active substances capable of changing the interfacial surface energy of the polymer and, therefore, lead to structural rearrangement, taking place at the interfacial surfaces. This section is concerned with the special features of this effect on deformation of glassy and crystalline polymers.
