| titleOfInvention | PROCEDURE FOR THE MANUFACTURE OF A GLASS LAMINATE. |
| abstract | Glass laminates comprise at least one layer of glass adhered to a layer of a novel ethylene copolymer (see Division C3) which comprises at least 35% by weight of ethylene units, units of one or more hydroxy or epoxy aliphatic or cycloaliphatic monoesters of acrylic or methacrylic acid, in which the (cyclo)aliphatic radical consists only of C, H and O and contains not more than 6 carbon atoms, and 0-55% by weight of units of a further comonomer having one ethylenic double bond which is an ester of acrylic or methacrylic acid (e.g. an alkyl ester) or a vinyl ester (e.g. vinyl acetate). The hydroxy or epoxy ester may be a hydroxyalkyl or glycidyl acrylate or methacrylate. Generally, the copolymer layer is present as an interlayer between sheets of glass or between a sheet of glass and a transparent or translucent, substantially rigid plastics material, e.g. polymethyl methacrylate, rigid polyvinyl chloride, polystyrene or a polycarbonate. Such a laminate can be prepared by sandwiching the copolymer layer between two sheets of glass or between a sheet of glass and a sheet of the plastics material, and heating the assembly to a temperature above the melting point of the copolymer (e.g. 110-130 C.) for a sufficient time and at a sufficient pressure to effect bonding the copolymer layer may be ridged or roughened to prevent blocking. In one particular embodiment, the assembly is placed in a flexible plastics or rubber bag which is then evacuated, and the bag and the assembly are heated in an oven or, preferably, in an autoclave at elevated pressure the assembly is then cooled before being removed from the bag. The glass surfaces to be bonded may, if desired, be pre-treated with an adhesion promoter, e.g. silanes of the type described in Specification 1,095,700. In examples, the copolymer is admixed with 4,41- thiobis - (3 - methyl) - 6 - t. - butylphenol), as antioxidant, before being formed into a film layer. The glass laminates are useful as safety glass in such applications as vehicle windscreens, bandit- or bullet-resistant windows or display cases, doors and wall panels in buildings, and transparent or translucent light fittings. |
