    摘要： The invention relates to a method of preparing crosslinked bitumen/polymer compositions having reduced emissions of hydrogen sulphide, in which, while operating at temperatures between 100° C. and 230° C. and with stirring, for a duration of at least ten minutes, at least one bitumen or mixture of bitumens is brought into contact with at least one polymer and at least one crosslinking agent, said crosslinking agent being represented by the general formula HS—R—SH where R represents a saturated or unsaturated, linear or branched, cyclic and/or aromatic hydrocarbon-based group having 2 to 40 carbon atoms, optionally comprising one or more heteroatoms, and that does not comprise a C═O carbonyl function and/or a O—C═O carboxylate function.

    摘要翻译： 本发明涉及一种制备具有减少的硫化氢排放的交联沥青/聚合物组合物的方法，其中在100℃和230℃之间的温度下并在搅拌下持续至少十分钟的时间， 使至少一种沥青或沥青混合物与至少一种聚合物和至少一种交联剂接触，所述交联剂由通式HS-R-SH表示，其中R表示饱和或不饱和的直链或支链， 具有2至40个碳原子的环状和/或芳族烃基，任选地包含一个或多个杂原子，并且不包含C = O羰基官能团和/或O-C = O羧酸酯官能团。
