摘要： This invention discloses a polymer composition, a cement slurry containing said polymer composition and a method of using the cement slurry to cement a borehole penetrating a subsurface earth formation wherein the polymer composition is made by polymerizing a vinylamide morpholine derivative with a styrene sulfonic acid salt in the presence of a humate. The polymer composition operates to reduce fluid loss from the cement slurry to the subsurface formation.
