Abstract

This study investigates the pivotal role of PE carbonyl groups in light resistance, with a focus on their impact during different stages of aging. Through the application of mechanochemical destruction, hydroperoxides are formed as initiators of photoaging in PE. Our findings reveal the superior effectiveness of hydroperoxides in early aging stages, while the presence of carbonyl groups exerts significant influence in later stages. The results emphasize the dual mechanisms driving photoaging in PE and provide valuable insights for developing strategies to enhance its durability and longevity. Highlights: The presence of carbonyl groups in polyethylene determines its resistance to light. Hydroperoxides formed during mechanochemical destruction initiate photoaging in polyethylene. Carbonyl groups play a significant role in the later stages of polyethylene photoaging. Keywords: Polyethylene, photoaging, carbonyl groups, hydroperoxides, light resistance.

Abstract

Antifriction and antifriction-wear-resistant composite polymer materials. The friction of raw cotton with a composite material has a complex nature. The mechanism of interaction of these bodies during friction is influenced by both molecular and mechanical processes.

Abstract

The article presents the results of research on the development of polymer composite materials with improved strength and antifriction properties based on high-density polyethylene (HDPE), as well as low-density polyethylene (LDPE) and modifying additives - Azerbaijani clays and SAE5W30 motor oil. It has been established that the introduction of 5–25% nanosized clays and 1–3% of the above oil into the composition allows thermoplastic materials with sufficiently high antifriction and other properties.

Abstract

Polyvinyl chloride (PVC) is one of the most bulky polymers produced both in Russia and abroad. The production of PVC and products based on it has been established at more than 100 enterprises in 50 countries around the world. In recent years, significant progress has been made in the production of PVC and products from it: pipes, profiles, including window films, sheets, PVC products.
