Abstract

Se describe un proceso para la producción de espumas de PET, el cual comprende la extrusión de una mezcla de PET, resina epóxica, catalizador que consiste de imidazol, derivados de imidazol o mezclas de los mismos más un agente de soplado, en donde la reacción de homopolimerización de la fase epóxica se lleva a cabo en el extrusor, corriente arriba de la introducción del agente de soplado. En comparación con los métodos de la técnica conocida, el proceso de la invención proporciona la ventaja de suministrar una espuma de PET estable, en la cual la estructura de las cadenas de polímero se mantienen sin alteración. El sistema por lo tanto presenta características de viscoelasticidad las cuales permiten que el homopolímero de PET/epóxico reciba la acción de expansión del agente de soplado, en la medida en que las capas más interiores y las capas más profundas de la espuma también tengan un espesor significativo.
