POLYMER COMPOSITION Russian patent published in 2007 - IPC C08L9/00 C04B26/14 C08K13/02 

FIELD: polymer materials.

SUBSTANCE: invention relates to make-ups of fine-grain polymer compositions and can be advantageously utilized in units subjected to considerable operation impacts and temperature variations, in particular for restoration of airdrome and road cement-concrete pavements and for protection of steel structures against corrosion. Polymer composition according to invention comprises 13.3% of oxidized butadiene-piperylene copolymer with dynamic viscosity 70-140 Ps (25°С, Hoppler viscosimeter) with butadiene-to-piperylene units weight ratio 58-42; 4.6% of epoxide resin "ED-20"; 1.5% of polyisocyanate; 66% of quartz sand; 0.7% of Laprol (modifying additive); and 13.9% of wollastonite "Woksil-100" (micro-reinforcing filler).

EFFECT: improved physico-mechanical characteristics of protective layers and increased adhesion of composition to steel.
