Изобретение относится к полимерам, применимым в качестве беззольных диспергирующих присадок и обеспечивающим сочетание диспергируемости, хороший запуск двигателя на холоду, низкотемпературные вязкостные свойства и нейтральное поведение по отношению к фторэластомерным материалам уплотнений двигателя. Полимеры могут быть получены полимеризацией одного или нескольких алкилметакрилатов с одним или несколькими гидроксиалкилметакрилатами при регулировании относительного отношения по массе мономерных компонентов с целью получения необходимого содержания атомов углерода в алкильных боковых цепях метакрилатного скелета полимера с достижением необходимой растворимости присадки.The invention relates to polymers, applicable as ashless dispersant additives and providing a combination of dispersibility, good engine start in the cold, low-temperature viscosity properties and neutral behavior with respect to fluoroelastomer materials of engine seals. Polymers can be obtained by polymerizing one or more alkyl methacrylates with one or more hydroxyalkyl methacrylates by adjusting the weight ratio of the monomeric components in order to obtain the required carbon content in the alkyl side chains of the methacrylate backbone of the polymer with the required solubility of the additive.
