Beschreibung
Zusammenfassung:	The invention provides polyoxyalkyl ether and a water reducing agent prepared from the polyoxyalkyl ether. The water reducing agent is prepared by modification with a polyether macromonomer that have important influences on properties of the water reducing agent. The polyoxyalkyl ether has excellent properties of common polyether and has a function of resisting soil adsorption. The function is achieved by a large-size high-steric-hindrance functional group at the tail end of the polyoxyalkyl ether. Because of the large-size high-steric-hindrance functional group, a polyoxyalkyl ether structural unit in the water reducing agent polymer cannot be inserted into pore spaces of soil, thus avoiding a large amount of soil adsorption of the water reducing agent.
