Abstract
Los polímeros de estirano expansibles en forma de perlas que se elaboran de acuerdo con el procedimiento conocido, todavía contienen cantidades relativamente altas de benceno. Según el procedimiento de esta invención, es posible elaborar polímeros de estirano con concentraciones muy bajas en benceno. Los polímeros de estirano elaborados de acuerdo con la invención, se expanden culurmente para formar partículas de material espuma.
