In the present invention copolymers of certain ethers and olefinic mono- acids (or salts or in some cases esters thereof) have been discovered to be effective superplasticizers for hydraulic cements. When admixed into wet cement compositions these polymeric compounds give the cement mixture higher slump and lower slumploss over time. Alternatively, the copolymers of this invention may be used in preparing a cement mixture requiring less water, to yield a hardened cement with greater compressive strength.

Title
Copolymers of ethylenically unsaturated ethers useful as hydraulic cement superplasticizers.
