The thermal resistance of coolant-lubricant liquid samples made on the basis of “Gala” washing liquid was studied with the help of the derivatrography method. The effect of polymer additives on their thermal resistance and penetrating and washing properties was determined. Методом дериватографії досліджено термічну стійкість зразків мастильно-охолоджу- вальних рідин, приготовлених на основі миючого засобу “Gala”. Виявлено вплив полімерних добавок МОР на їх термічну стійкість та проникаючі і миючі властивості. 

In the article the concentration dependencies of dynamic viscosity and surface tension of aqueous solutions of polyvinylpyrrolidone and polyacrylamid were researched. It was shown that polyvinylpyrrolidone is more preferable polymeric constituent for synthetic lubricating liquids. When using the polyvinylpyrrolidone, a significant increase of corroison activity of technological liquids is likely to occur and can be decreased with another polymeric constituent - polyacrylamid and corrosion inhibitors.
