Abstract
A study has been made of the influence of crystallization of glassy polyethylene terephthalate (PETP) stretched in an adsorption-active medium on its structure and adsorption properties. It was found that the annealing of strained PETP specimens in the same liquid medium results in stable highly porous materials whose structure does not depend on the drying process or on repeated humidification. It is shown that these materials are capable of adsorbing iodine and an organic dye (Rhodamine S) from aqueous solutions. Major changes in the structure and adsorption behaviour of PETP are obtainable by varying the degree of prior drawing of the polymer in an adsorption active medium. PETP specimens prepared with crystallization of the polymer are capable of adsorbing considerable amounts of various substances from the gaseous phase as well. This makes it possible to obtain some additional data on the structure of the materials.
