Laminated glass structures and process for production thereof

摘要: A laminated safety glass structure which comprises at least two sheets bonded to each other through an interlayer of a plasticized polyvinyl acetal resin treated with specific modified siloxane alone or together alkali metal alkaline earth salt organic mono- di-carboxylic acid. This has highly improved penetration resistance along superior transparency, aging and weatherability, is suitable for use as windowpanes in transportation facilities buildings.
