Abstract
Procedimiento para la obtención de materiales sintéticos fermentosos, termoplásticos empleándose fermentos líquidos cuyos punto de ebullición se encuentre por debajo de la temperatura de reblandecimiento del material sintético, caracterizado, porque el material sintético se trata preferentemente en forma de grano fino, por ej. granulado, con un fermento, que disuelva el material sintético o esponja fuertemente a éste y con un fermento que sea insoluble en el material sintético o también con una mezcla de ambos productos, a temperaturas que sean inferiores a la de los puntos de ebullición de los fermentos empleados o de sus mezclas, y por el material sintético fermentoso esponjado se vuelve a extraer, por disolución, parcialmente el fermento soluble en el material sintético.
