An open-cell cross-linked polyolefin foam possessing extremely high non-flammability is produced by dispersing a thermally expansible graphite in an adhesive agent and applying the resultant adhesive agent mixture to at least part of the surface of a flame-retardant open-cell cross-linked polyolefin foam. As the flame-retardant open-cell cross-linked polyolefin foam, an open-cell cross-linked polyolefin foam which possesses a polymer of a phosphorus type flame-retarding agent in the interior and the surface of the open-cell foam or an open-cell cross-linked polyolefin foam which contains a halogen type flame-retarding agent in the cell membranes thereof and possesses a polymer of a phosphorus type flame-retarding agent in the interior and the surface of the open-cell foam is preferably used.

A process for producing a monomolecular built-up film of monomolecular layers of a silane surfactant is described. In the process, the silane surfactant is chemically adsorbed on a hydrophilic surface of a substrate and is subjected to irradiation of a high energy beam or plasma treatment in an active gas atmosphere to activate the monomolecular layer. This activated layer is further adsorbed with the silane surfactant to form a built-up film. The beam irradiation or plasma treatment may be effected in a desired pattern. The beam irradiation or plasma treatment and the further adsorption are repeated until the desired number of the monomolecular layers is obtained.
