Annotation
The article investigates the optimal conditions, structure, and properties of polymer sulfur obtained from local sulfur raw materials. A composition was developed using secondary phenol and sulfur. Sodium hydroxide was utilized as an initiator in creating the composition. IR spectroscopy was employed to determine the optimal conditions for polymer sulfur. Based on the research results, the interactions between bitumen and mineral material were studied, focusing on the mechanical theory and electrostatic theory of adhesion properties.
