This work is devoted to the results of experimental researches antifrictional and non-wear properties plastic greasing with liquid crystal additives - carboxylates of copper, forming in mesophase the column form over molecular structures. The choice of additives for researches is caused by the sizes of their molecules. Synthesis of additives was carried out by various methods (fusion and mechanical activation method in crasher of shock-reflective type). Tribological researches have been executed by friction machine. Researches have shown that introduction as additives to greasings on the basis of lithium the investigated carboxylates of copper allows to lower friction coefficient in 1.5-3.45 times that as a whole allows to reduce losses from friction in tribological connection. Wear of friction pairs elements decreases in 1.4-4.8 times, that allows to increase further the resource of details friction pairs of agricultural machines and the equipment. Tribological characteristics Improvement is connected with the fact that at transition in amorphous condition the given connections collected in hexagonal domains, are occupy certain position concerning the friction surface, having thus lowered durability at shift deformation. It is revealed that for investigated carboxylates of copper at their additive in lubricant on the basis of lithium is obviously observed dependence on concentration of an additive in a range from 1 to 20 weights %: if above its concentration it is more decrease in coefficient of friction and wear. The received results show perspectivity copper сarboxylates at use as antifrictional and non-wear additives to plastic lubricant on the basis of lithium.carboxylateswearlubricantfrictionadditivemesophaseкарбоксилатыизноссмазкатрениеприсадкамезофаза[Усольцева, Н.
