FIELD: chemistry.
SUBSTANCE: polymer material contains acrylic polymer, chlorine-containing polymer and inorganic hydroxide. The acrylic polymer is selected from a homopolymer of alkyl(alc)acrylate or copolymer of alkylmethacrylate and alkylacrylate. The chlorine-containing polymer contains 5-70 wt % halogen. The inorganic hydroxide is selected from magnesium hydroxide, zinc hydroxide or mixtures thereof, except a mixture of magnesium hydroxide and zinc oxide or magnesium hydroxide and zinc stannate. Weight ratio between the chlorine-containing polymer and the acrylic polymer is at least 0.3. Polymer material is obtained by mixing the chlorine-containing polymer and inorganic hydroxide in molten acrylic polymer. The polymer material is used to make articles and structural elements in construction.
EFFECT: inorganic hydroxide gives the material high resistance to atmospheric effects.
