Abstract

Una composicion gelificante dieléctrica que exhibe una transicion líquido-gel termo-reversible a una temperatura de transicion Tt, en donde el gelcomprende un aceite y un gelificador con un copolímero en bloque que comprende un bloque olefínico y almenos otro bloque que comprende anillos aromáticos ensu estructura de espina dorsal, en donde cada uno de los dos bloques tiene un peso molecular superior a 3.000 g/mol y en donde el bloque de anillos aromáticosen su estructura de espina dorsal exhibe una estructura de espina dorsal rígida y una solubilidad en el aceite que depende de la temperatura. La composiciongelificante se obtiene preparando el copolímero en bloque por medio de una reaccion de condensacion y anadiendo entonces el copolímero resultante a un aceite auna temperatura por encima de la temperatura de transicion de la composicion gelificante. La composicion gelificante se emplea como impregnante en undispositivo eléctrico aislado de corriente continua que tiene al menos un conductor y un sistema aislante impregnado. El sistema aislante comprende una partesolida dieléctrica, aislante de la electricidad, con una estructura porosa, fibrosa y/o estratificada impregnada con una composicion gelificante dieléctrica.
