FIELD: polymer materials.
SUBSTANCE: group of inventions relates to a device and method for studying the gas permeability of polymer materials. A device for studying the barrier properties of polymer materials is disclosed, which includes a diffusion cell, which consists of three independent chambers that allow simultaneous study of gas permeability to three different gases, a belt-pulling mechanism of a film polymer material, a gas chromatograph and a dispenser tap. A method for studying the barrier properties of polymer materials using this device is also disclosed.
EFFECT: group of inventions provides the ability to study gas permeability for three gases simultaneously, and also makes it possible to reduce the research error.
