[Also in Division C3] A method of adhering two materials, at least one of which is a polyester, polyamide o cellulosic material, comprises applying to at least one of the surfaces to be adhered a high molecular weight substance (see Division C3) containing a plurality of side-chains terminated by a group of the formula where R represents H, halogen, alkyl, alkoxy, acyloxy, acyl, carboalkoxy, cyano or nitro and R 1 represents an alkylene group of at least two carbon atoms, and bringing together the two surfaces to be adhered, preferably while also heating. The high molecular weight substance is suitably applied from solution in a solvent such as benzene. Adhesion may be effected in the presence of an assistant, e.g. halogen (other than fluorine), a halogenreleasing (by heating) compound or mixture of compounds, a halogen-containing polymerizable monomer, or an isocyanate or an isocyanateyielding (by heating) compound. Also, where the high molecular weight substance is based on a diene polymer, benzoyl peroxide may be present in the adhering method. The polyester, polyamide or cellulosic material is adhered to like material or to other types of material, e.g. polystyrene, polycarbonates, polyphenylene oxide, polymethacrylates, diallyl phthalateacrylonitrile - butadiene - styrene copolymers, melamine - formaldehyde polymers, phenolformaldehyde polymers, urea - formaldehyde resins, metals, glass, leather, wood and vulcanized or unvulcanized natural or synthetic rubber. The polyester may be polyethylene terephthalate; the polyamide polyhexamethylene adipamide; and the cellulosic rayon. In examples, the adhered materials take the form of films, foils, sheets and tyre cords.</p> |
