Abstract
L'invention concerne un procédé de préparation de polyvinyl butyral par réaction d'alcool polyvinylique en solution aqueuse et d'aldéhyde butyrique. Ce procédé se caractérise en ce que ladite solution aqueuse comprend entre 8 et 15 % en poids d'alcool polyvinylique, en ce qu'on y incorpore un catalyseur acide et un émulsifiant, en ce que l'on introduit dans le mélange ainsi obtenu, maintenu entre 5 et 12 degrés C et sous agitation, de l'aldéhyde butyrique en quantité suffisante pour réagir avec 75 à 88 % de l'alcool polyvinylique du mélange, en ce que le mélange résultant est maintenu sous agitation pendant une durée supérieure à 30 minutes à une température de 8 à 15 degrés C, en ce que la température du mélange est ensuite élevée jusqu'à une valeur maintenue entre 60 et 80 degrés C, en ce que l'on incorpore une base dans le mélange jusqu'à obtention d'un pH compris entre 9 et 11. Application notamment à la fabrication de pare-brise d'automobile.The invention relates to a process for preparing polyvinyl butyral by reacting polyvinyl alcohol in aqueous solution and butyric aldehyde. This process is characterized in that said aqueous solution comprises between 8 and 15% by weight of polyvinyl alcohol, in that an acid catalyst and an emulsifier are incorporated therein, in that one introduces into the mixture thus obtained, maintained between 5 and 12 degrees C and with stirring, butyric aldehyde in an amount sufficient to react with 75 to 88% of the polyvinyl alcohol of the mixture, in that the resulting mixture is kept under agitation for a period of time greater than 30 minutes at a temperature of 8 to 15 degrees C, in that the temperature of the mixture is then raised to a value maintained between 60 and 80 degrees C, in that a base is incorporated into the mixture until obtained with a pH of between 9 and 11. Application in particular to the manufacture of automobile windshields.
