The present invention provides an amine or polyamine, which has a surface activity not inferior to a solid tallow-based amine and an excellent workability. A salt of the amine is suited for emulsifying asphalt and the like, and also provides an asphalt emulsion composition which is obtained by using the salt and which has a quick setting property. Namely, the prevent invention provides a polyamine represented by formula (1), a process for producing the amine, and an asphalt emulsion composition containing a water-soluble salt of the amine, wherein R is a straight or branched hydrocarbon group having 8 to 22 carbon atos; x is a number of 1 to 5; and each of y and z is a number of 0 to 5 with the proviso that both of y and z are not 0 at the same time.
(ZH) 本发明提供了一种胺或多胺，具有不次于固体动物脂基胺的表面活性以及优良的可施用性。这种胺的盐适用于乳化沥青等，还提供了使用该盐获得的沥青乳化组合物，该组合物具有快速固化性能。本发明提供了由式(1)表示的多胺及其制备方法，以及含这种胺的水溶性盐的沥青乳化组合物。其中R是有8-22个碳原子的直链或支链烃基；x是1-5的数；y和z各自是0-5的数，条件是y和z不能同时为零。
