ABSTRACT:
A rubber composition made of a diene rubber having such excellent properties as heat resistance and mechanical strength and organopolysiloxane or fluoropolymer as a lubricating substance. The lubricating substance may contain isocyanate or cyanate groups, which will react with the hydroxy groups which exist on the surface of a filler usually applied to the diene rubber, thus securely keeping the lubricating substance in the molecular structure of the composition. A liquid diene polymer containing hydroxy groups and having a good compatibility with the diene rubber may be further added to the composition so that its hydroxy groups will react with the isocyanate or cyanate groups in the lubricating substance.
The liquid diene polymer may contain epoxy groups instead of hydroxy groups, whereas the lubricating substance containing such functional groups as amino, carboxyl, hydroxy or mercapto groups so that the exoxy groups in the former and the functional groups in the latter will react with each other. The composition may further contain an isocyanate compound containing isocyanate groups, with the liquid diene polymer containing hydroxy groups. In this arrangement, the hydroxy groups in the liquid diene polymer will be replaced with the isocyanate groups, which in turn will react with the functional groups in the lubricating substance.
