Synthesis of High Solid Polycarboxylates for Cement Superplasticizers |
| abstract |
The present invention provides an efficient method of forming high solids polymeric polyacids or comb polymers useful as superplasticizers or dispersants comprising: at (i) 0.01 to 1 wt. In the presence of a water-soluble free radical initiator or redox couple and (ii) 2 to 22% by weight of one or more phosphorus oxide-containing compounds, the wet reaction mixture is heated to 80 to 100° C. for a first period of time, and then sequentially heated to a second temperature of 150 to 250° C. for a second period of time, the wet reaction mixture having a solids content of 80 to 99% by weight and comprising 15 to 60% by weight of one or more ethylenically unsaturated Acid or salt thereof, 37 to 76.99% by weight of one or more polyether polyols, alkyl polyether polyols, polyetheramines or alkyl polyethers, all weights are based on the total weight of the wet reaction mixture . |
