Abstract

Un procedimiento de fabricación de material plástico polistireno de propiedades físicas perfeccionadas, caracterizado porque comprende la incorporación en el polistireno de más del 20 por ciento de su peso de una goma sintética no vulcanizada elaborada en frío, mediante la mezcla del polistireno y la goma en forma sólida y divididos y homogeneizándose mediante reblandecimientos y elaborando la mezcla bajo la acción de calor.
