COMPOSITIONS CONTAINING POLYMERS WITH THIOL END GROUPS AND SULPHUR-CONTAINING ETHYLENE-NON-SATURATED SILANES, AS WELL AS RESPECTIVE HARDENED HERMETICS Russian patent published in 2015 - IPC C08L81/02 C08K5/54 C09K3/10 

FIELD: chemistry.

SUBSTANCE: invention relates to compositions, containing polymer, which has thiol terminal groups, as well as are described proper products, such as hermetics, which contain polymers, obtained from such compositions, which can be applied for aerospace purpose. Composition contains polythioether, which has thiol terminal groups, sulphur-containing ethylene-non-saturated silane ipolene, which includes polyvinyl ether Invention also relates to method of obtaining hardened composition of hermetic, which includes sedimentation of hermetic on substrate and interaction on non-hardened composition of hermetic by actinic irradiation.

EFFECT: invention is characterised by high adhesion to substrates of aircraft, such as substrates of fuel tanks.
