POLYMERIC COMPOSITION Russian patent published in 2008 - IPC C09K3/10 C08L25/10 

FIELD: chemistry.

SUBSTANCE: oxidised styrene-butadiene thermoplastic elastomer is used as the bonding agent, which has at its ends macromolecules of reactive carboxyl or hydroxyl groups, with a prevalence of the later; as the hardening agents of the polyisocyanates with a fraction of the total mass of the isocyanate groups not less than 30%, as the filler fine-dispersed mineral powders or pigments, as the modifying components - micro-reinforcing filler - wollastonite, as the plasticiser - dibutyl phthalate, additionally added is a curing agent - oil-thallous siccative and a stabiliser - styrenated diphenylamine BTC-150 or BC-30A; with the following ratio of components by mass %: oxidised styrene-butadiene thermoplastic elastomer 52.0-60.0; hardening agent polyisocyanate 7.0-9.0; hardening agent siccative 1.2-1.7; filler - fine-dispersed mineral powder or inorganic pigments 20.0-29.0; plasticiser - dibutyl phthalate 0.6-0.8; modified additive - wollastonite 6.0-8.0; phenol type stabiliser BTC-150 BC-30A 1.2-1.5, and the composition does not contain any organic solvents.

EFFECT: reduction in the shrinking deformation, increasing hardness, lowering the temperature of using the composition.
