Abstract

Procedimiento y preparación de composiciones de betún-polímeros, que consiste en mezclar bajo agitación a una temperatura de 130 a 230ºC, de 80 a 98% en peso de un betún de penetración comprendido entre 30 y 220, y de 2 a 20 % en peso de un copolímero polisecuencial de masa molecular media comprendida entre 30.000 y 300.000 elegido en el grupo estireno-dieno, conjugado y en mantener esta mezcla al menos dos horas a esta temperatura, y después en añadir de 0,1 a 3% de azufre elemental con respecto al betún manteniendo las mismas condiciones de agitación y de temperatura durante 20 minutos como mínimo, caracterizado porque la secuencia dieno conjugado se elige en el grupo del butadieno carboxilado y del isopreno.Procedure and preparation of bitumen-polymer compositions, which consists of mixing under agitation at a temperature of 130 to 230ºC, from 80 to 98% by weight of a bitumen penetration between 30 and 220, and from 2 to 20% by weight of a polysequential copolymer with an average molecular weight between 30,000 and 300,000 chosen from the styrene-diene group, conjugated and maintaining this mixture for at least two hours at this temperature, and then adding 0.1 to 3% elemental sulfur with with respect to bitumen, maintaining the same conditions of agitation and temperature for at least 20 minutes, characterized in that the conjugated diene sequence is chosen from the group of carboxylated butadiene and isoprene.
