FIELD: chemistry.
SUBSTANCE: invention relates to production of waterproofing materials in form of profiled objects - cords, meant for sealing joints in unit construction and which provide for waterproofing through fast water regain. The polymer sealing composition contains, wt %: polymer - synthetic ethylene-propylene triple rubber - 23.78-86-80, natural bentonite - 8.68-71.34, sodium carbonate - 0.09-2.38, titanium white - 2.38-4.34 and colouring pigment - 0.09-0.12.
EFFECT: increased degree of water regain, resistance to effect of atmospheric factors, increased frost- and ozone resistance, cohesion strength and elasticity after the material dries.
