A new chemical variant of superplasticisers is the so-called polycarboxylate ether. These materials are characterised by a polymethacrylic or allyl acid back bone with side chains attached comprising methoxy-polyethylene glycol groups. 63,64 A chemical representation is given in Fig. 14.41.

Polycarboxylate ethers (PCE) are used as superplasticizers in concrete production. Safety. Polycarboxylates are poorly biodegradable but have a low ecotoxicity. In the sewage treatment plant, the polymer remains largely in the sludge and is separated from the wastewater.
