FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to water-dispersed powdery polymeric compositions comprising one or some components with pozzuolanic properties and to a method for their using. Method involves addition of meta-kaolin as an additive with pozzuolanic properties to water-dispersed polymeric powdery composition based on homo- or copolymers of one or some monomers chosen from the group comprising vinyl ester of direct or branched alkyl carboxylic acids with 1-15 carbon atoms, methacrylic acid ester and ester of acrylic acid and alcohol with 1-15 carbon atoms, vinyl aromatic compound, olefin, diene and vinyl halide, protective colloidal substance and, optionally, agents against caking. Invention provides preparing water-dispersed powdery composition that is added to mortar and provides enhancing its mechanical strength in hardened state.
EFFECT: improved preparing method, enhanced and valuable properties of composition.
