| titleOfInvention | Ethylene Copolymers and Laminates made therewith |
| abstract | 1,166,443. Glass laminates. IMPERIAL CHEMICAL INDUSTRIES Ltd. 26 Jan., 1967 [14 Feb., 1966], No. 6389/66. Heading B5N. [Also in Division C3] 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 4,4<SP>1</SP>- 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. |
