Terminal alkenyl nonsaturated polyether and purpose thereof
The invention provides terminal alkenyl nonsaturated polyether shown in a formula (1), and the invention also provides a purpose of the terminal alkenyl nonsaturated polyether. According to the provided terminal alkenyl nonsaturated polyether, a polyether chain segment can be adjusted through different structural units, so that dispersion effect of a prepared water reducer on concrete is increased, and water-reducing rate of a polycarboxylic acid water reducer and slump constant are obviously increased. The preparation method has the advantages of simple operation, mild condition and easy industrial application.
