Polyethylene and polypropylene manufacture produce low molecular weight polyethylene and atactic polypropylene, which are multi-tonnage by-products. One of the most essential environmental problems is to solve the problem of their practical application or disposal. The goal of this paper is to provide a theoretical rationale and recommendations for the practical application of low-molecular-weight polyethylene and atactic polypropylene in the field of moisture protection for various materials. The findings of research into chemical compounds based on modified low-molecular-weight polyethylene and atactic polypropylene for use as hydrophobic and anticorrosive protection for wood, concrete, and steel are reported. Thermal oxidation was used to change the properties of polymers. Water absorption indicators, wetting edge angles, and adhesive strength values of the protective polymer layer to the surface of the samples were all determined. The preliminary development of the texture by applying a pattern to the surface or treating it with low-temperature plasma, followed by the application of a protective coating, is proven to increase the hydrophobic qualities of the suggested compositions using the example of wood. It is suggested a kinetic equation for moisture diffusion in the volume of a capillary-porous wood structure. X-ray phase analysis and IR spectroscopy were used to highlight the structural properties of changed polymer compositions. It is proposed that the investigated compositions be used as water-repellent agents to protect various materials and goods based on them from moisture and environmental corrosive effects.
