摘要:
The present invention relates to an-economically and ecologically advantageous process, which is easy to carry out, for the preparation of specific polyethylene glycol diesters of 2-(4-chloro-2-methylphenoxy)-propionic acid, and to the substance mixture obtainable by this process and the use thereof as a root penetration inhibitor in building materials and insulating compositions, such as, for example, bitumen.
