Abstract: The invention relates to a hyperfiltration membrane containing a supporting layer and a separation layer. The membrane is characterized in that the separation layer consists of a crosslinked monomolecular film of molecules, the molecules of the separation layer in the uncrosslinked state being surfactants or surfactant-like lipoids containing at least one hydrophobic chain and at least one hydrophilic group, the hydrophobic chains of these molecules being oriented mainly perpendicularly to the plane of the membrane and parallel to the diffusion direction after crosslinking and the molecules of the separation layer being crosslinked with one another through functional groups in at least one of their hydrophobic chains and/or through functional groups in at least one of their hydrophilic groups.

Abstract: Process for the direct joining of rubber to metal surfaces by vulcanization using a rubber mixture containing the additives common for sulfur vulcanization wherein either the rubber mixture contains additionally tellurium, tellurium alloys and/or tellurium compounds as bonding aid, or that tellurium, tellurium alloy and/or tellurium compound is applied on the metal surface before vulcanizing.
