Abstract
The influence of the molecular weight and composition of polyalkyl (meth) acrylate thickeners on the properties NS-3 ultralow pour point naphthenic base oil (Nynas, Sweden) was determined. Using standard experimental techniques, it has been shown that copolymers of higher alkyl methacrylates with C12-C15 alkyl groups, containing 5-15% methyl methacrylate or butyl methacrylate units and having an average molecular weight Мn = 18000-20000, have good thickening properties and high resistance to mechanical destruction (which are not inferior to the indicators of the used foreign additive Viscoplex 0-220). The results made it possible to develop a thickening additive K-64-03 for low pour point transmission oil, which can be used in highly loaded machinery in the winter conditions of the Far North. Additive K-64-03 exhibits the required thickening properties at elevated and negative temperatures, does not worsen the ultra-low pour point of the base oil (below minus 70°C) and has a high resistance to mechanical destruction.
