| Application | Ethylene glycol monovinyl polyethylene glycol ether (EPEG) is a reactive macromonomer for synthesizing polycarboxylate superplasticizers (PCE). It directly undergoes free-radical copolymerization with unsaturated carboxylic acid monomers (such as acrylic acid) to produce high-performance water-reducing admixtures with superior slump retention. | |
