Abstract

Un método para recuperar poli (vinil butiral) (PVB). El proceso comprende mezclar una composición de alimentación de PVB con un solvente, un catalizador y, opcionalmente, butiraldehído para producir una composición que contiene PVB equilibrada. La composición de alimentación de PVB comprende por lo menos dos composiciones que contienen PVB diferentes. Una etapa adicional incluye determinar un contenido de polialcohol vinílico (PVOH) residual de la composición que contiene PVB equilibrada. Una etapa adicional incluye ajustar la cantidad de butiraldehído utilizado en la etapa de mezclado en base al contenido de PVOH residual determinado.
