ABSTRACT OF THE DISCLOSURE A polymeric composition comprises a mixture of components taken in the following ratio, in parts by weight: (polypropylene glycol)diurethanediepoxide.....100 diglycidyl ether of bisphenol A....... 10 to 150 curing agent which is a mixture of m-phenylenediamine and aniline taken in a weight ratio of 0.9 to 1:1...13 to 40. The above ratio of (polypropylene glycol)diurethanediepoxide and di- glycidyl ether of bisphenol A as well as the introduction of the required amount of the curing agent ensure a high elasticity, in addition to a high adhesive power and high mechanical strength. This composition can be used for protecting metals from corrosion particularly for anti-corrosion covering of heat supply lines, oil pipelines and gas pipelines, wherein the product which is covered has a temperature of 80 to 120°C. Also, because of high tackiness towards iron and concrete, and because of its good elasticity, the composition of the present invention may be used as a sealing compound for sealing joints and as a glue of high adhesive power.
