FIELD: chemistry.
SUBSTANCE: method involves drawing a polymer sample - an isotropic film of amorphous or crystalline polymer in an adsorption-active liquid medium in isometric conditions. The dried stretched film is held in a solution of a functional substance in a solvent until pores are filled with possibility of regulating content of the functional substance in the pore system. The solvent used does not cause swelling of the polymer from which the stretched film is made. The solvent is removed by drying. The film is then cut, granulated and used as a polymer additive.
EFFECT: invention provides high degree of dispersion of said functional additives in a polymer matrix.
