Annotation:  The removable prostheses of various design are used for the treatment of partial teeth loss. An acrylic plastic of hot polymerization is used for manufacture of bases of these prostheses. This material has dis-advantages, for example, long time of manufacturing the prostheses and presence of free monomer of methylmethacrylate. It can cause the allergic stomatitis. The search of new basic materials is actually. The article is devoted to the study of the chemical, physical and mechanical properties of the light-cured mate-rial «Nolatek» and the correspondence of these properties to the requirements of the GOST 31572-2012. Here we study color stability, polishability, translucency, lack of pores, bending strength, modulus of elasticity, resistance to cracks, connection with artificial plastic teeth, water absorption and solubility. The properties of samples of the material are investigated according to the approved methodologies of the GOST. The chemical composition of «Nolatek» is established. As a result of the study, the complete con-formity of the properties of this material to standards is established. These results allow us to recommend the light-cured material «Nolatek» for clinical use in dentistry
