The influence of polymer additives in the form of polymer dispersions and redispersible polymer powders based on vinil acetate-ethylene on physico-mechanical properties of oil-well Portland cement is considered. It is shown the positive changes in the technical properties of cements with polymer additives. It was fixed that poly-mer additives promote the formation of polymer pellicles. They provide high adhesive and elastic properties of cement stone.
