摘要：

It was shown previously that the introduction of bis(alkylphenyl) dithiophosphate fragments into a polymethacrylate macromolecule leads to the appearance of antioxidant and detergent-dispersant properties, while the thickening (V. I. -improving) and pour-depressant properties are retained. In formulating multigrade oils, V. I. improvers are combined with dithiophosphate additives to improve the lubricating properties of the compounded oil. However, some metal dithiophosphates are poorly compatible with V. I. improvers of the polymethacrylate type. This study investigated the antiwear and antiscoring properties of copolymers of alkyl methacrylates and diethylaminoethyl methacrylate, modified with dithiophosphoric acids of various structures.
