Abstract The results of the research into the influence of polymer components ratio – high density polyethylene and low density polyethylene, into the regularity of changes in thermomechanical properties are presented. The deformation was measured at varying temperatures and at a constant load of 0.5 kg/cm2. The concentration of low density polyethylene varied from 10 […]
Abstract The electrochemical corrosion prevention of engines and mechanisms is a task of great national, economic and defense importance. Lubricating oils commonly used in engineering do not have sufficient protective properties and are unable to effectively protect it from corrosion, both during operation and during short-term and long-term inactivity. One of the simplest and most […]
Abstract Alkaline synthesis of double co-oligomers of 2-propenylphenol and formaldehyde (synthons) was carried out at 92-950C, for 3 hours and ratio of 1:2.5 mol (their yield are 93% of theory)Interaction of maleic anhydride with the obtained olygomers at 800C in the presence of 0.5% benzoyl peroxide for 10 hours produced copolymers of a three-dimensional cross-linked […]
Abstract By free radical addition of ethanedithiol to alkyl- and cycloalkyl-substituted methylene dioxolanes, the bis-adducts tested then as a plasticizer for PVC have been obtained. It has been established as a result of the carried out investigations that the introduction of the synthesized compounds into PVC composition improves the physical-mechanical properties, which has been connected […]
