Abstract

Un procedimiento para la preparación de resinas de estireno, reforzadas con polímero cauchoso y sustancialmente exentas de gel, caracterizado porque comprende las etapas de: a) adicionar un material monomérico, elegido del grupo constituido por monómeros y mezclas monoméricas capaces de formar un polímero cauchoso mediante polimerización, a una suspensión de perlas de una matriz polimérica rígida que comprende un polímero de un compuesto estirámico; b) poner en contacto la matriz polimérica y el material monomérico bajo condiciones en las que dicho monómero es absorbido por dicha matriz, con lo que se forma una suspensión de las perlas de polímero estirénico que tienen dicho material monomérico distribuido de forma sustancialmente uniforme; c) efectuar la polimerización de suspensión de dicho material monomérico con un catalizador de radicales libres, con formación in situ de un polímero cauchoso parcialmente injertado en la matriz polimérica.
