NATURE OF POLYSILOXANES AND ITS EFFECT ON THEIR ACTION AS ADMIXTURES TO HYDROCARBON LUBRICATING AGENTS,
Abstract
To explain the effect of the nature of polysiloxanes on the improvement of the lubricating effect of hydrocarbons during their addition into same, the antiwear and antifriction properties of mixtures of 1, 1-di(o-xylyl)-ethane with polyethylsiloxane, polymethylsiloxane and two polymethylphenylsiloxane liquids were investigated. Mutual strengthening of the lubricating effect of polysiloxanes and hydrocarbons depends to a large degree upon the nature of polysiloxanes, which by degree of reducing their activity as admixtures, improving the lubricating qualities of hydrocarbons, are arranged in the following series: Polyethylsiloxane > polymethylsiloxane > polymer 1 > polymer 2. An assumption was made that this is connected with a rise in thermooxidizing stability during the change in polysiloxane chanins of ethyl side groups into methyl and phenyl. Mutual strengthening of the lubricating effect of hydrocarbons and polysiloxanes may appear not only then when they are soluble in each other but also when they are emulsified in hydrocarbon media.
