Abstract
Un proceso para la produccion de artículos de poliolefina huecos, comprende introducir una combinacion estabilizadora en la poliolefina, la cualcombinacion comprende: a) por lo menos un compuesto seleccionado de entre el grupo consistente enfosfitos y fosfonitos orgánicos, b) uno o más compuestosseleccionados de entre el grupo consistente en: (i) derivados de hidroxilaminas, y (ii) derivados de oxidos de amina, y c) por lo menos un compuestoseleccionado de entre el grupo consistente enlos oxid os de amina estabilizantes, llenar un molde con esta mezcla, calentar este molde en un horno a más de280*C, de manera tal que la poliolefina estabilizada se funda, hacer rotar el molde alrededor de por lo menos dos ejes, distribuyéndose elmaterial p lástico enlas paredes, enfriar el molde mientras todavia está rotando, abrirlo, y extraer el artículo hueco resultante.
