    Abstract: An extreme-pressure additive and a friction coefficient modifier each composed of a compound having a group of general formula (I) (wherein R1 to R3 are each hydrogen or methyl, at least one of R?2 and R3¿ being hydrogen) in the molecule; a load-bearing baking fluid, a wear-resistant fluid and a heat-polymerizable substance containing them respectively; and preferably a flame-retardant fluid containing the compound. The above additive and modifier are excellent in performance and are suitably usable for lubricating oils, metal working oils and hydraulic oils. When exposed to high temperature, the above flame-retardant fluid is heat-polymerized to inhibit the vaporization of flammable substances, thus preventing a fire. Therefore, the fluid is suitable for lubricating oils, metal working oils, hydraulic oils, heat treatment oils, grease and so on.

    Abstract: A process of producing powder rubber having a particle size in the range of between about 50 microns and 180 microns is described. The process removes metal, fiber and other foreign materials from ground used tire rubber particles. The processed used tire rubber particles are embrittled by contact with a cryogenic liquid. The embrittled rubber particles are milled in a conical mill. The comminuted rubber particles exit the conical mill at a temperature in the range of between -15 degrees C and -30 degrees C. The powder rubber produced can vulcanize as easily or even more easily than virgin rubber.
