SYNTHETIC POLYMER RHEOLOGY MODIFIER AND WATER RETENTION AGENT REPLACEMENT FOR CELLULOSE ETHER IN CEMENT COMPOSITIONS

摘要

The present invention provides substantially nonionic brush polymers having pendant polyether groups, preferably poly(alkylene glycol) groups, which polymers are useful as synthetic polymer substitutes for cellulose ethers in mortars and hydraulic binders. The brush polymers are preferably crosslinked, such as with ethylene glycol di(meth)acrylates.
