Аннотация: Deformation of amorphous glassy poly(ethylene terephthalate) (PET) films in liquid adsorption-active media (AAMs) by the crazing mechanism has been studied. The crazing has been shown to be an effi-cient method for the formation of a finely dispersed mesoporous structure in the polymer. A technique hasbeen developed for stabilizing the structure of crazed PET by its annealing in the presence of an AAM underconditions that prevent the polymer from shrinkage. The porosity and vapor permeability of the obtainedPET-based materials have been studied as depending on the deformation and annealing conditions. It hasbeen revealed that the stability of the mesoporous structure formed in PET films after their annealing in theAAM results from polymer crystallization. The obtained structure is characterized by anisotropic relief andwettability of the surface.
