Abstract
Se describen procesos para recuperar poli(vinil butiral) rígido de una lámina de múltiples capas de poli(vinil butiral) plastificado que contiene el poli(vinil butiral) rígido y poli(vinil butiral) blando. Los procesos incluyen la molienda de la lámina de múltiples capas de poli(vinil butiral) plastificado para obtener un granulado; adicionar el plastificante adicionado para el granulado para remover por lo menos una porción del poli(vinil butiral) blando y separar físicamente el granulado de la solución resultante.
