  • Process for producing glass laminates
    Publication number: 20090126859
    Abstract: A non-autoclave process of manufacturing a glass laminate comprising: (a) providing an assembly comprising (i) a first rigid sheet layer, and (ii) an interlayer sheet comprising a copolymer comprising units from an alpha olefin and about 17 weight % to about 25 weight % of units from an alpha, beta-ethylenically unsaturated carboxylic acid, groups wherein about 1 to about 100 mole % of the carboxylic acid groups are neutralized with metal ions; and (b) forming the glass laminate from the assembly without use of an autoclave comprising in sequence (i) applying vacuum to the assembly; and (ii) applying heat to the assembly while still under vacuum.
