Abstract: FIELD: chemistry. 
     SUBSTANCE: present invention pertains to silane binding substances, methods of making them and their use in making rubber. The invention seeks to make silane binding substances, in which the released hydrolysable groups help improve the rubber mixture and/or properties of the end product. The proposed composition contains at least, one silane binding substance for binding an elastomer and filler. The silane contains at least, one hydrolysable group, which, after mixing the silane and the elastomer and the filler, which is released, obtaining a compound which further improves process properties of the mixed composition or properties of the end rubber product, or either of the two. The silane binding substance is chosen from a group consisting of silanes, separate structures of which are presented in at least one of the following general formulae: [J-S-G 1 -(SiX 2 X 3 )][-Y 2 -(X 2 Si-G 1 -S-J)] m -X 1 ; [X 1 X 2 X 3 Si-G 2 -S x -G 3 -Si(X 2 X 3 )][-Y 2 -(X 2 Si)-G 2 -S x -G 3 -(SiX 1 X 2 X 3 )] m -X 1 ; [X 1 X 2 X 3 Si-G 2 -S x -G 3 -Si(X 2 X 3 )][-Y 2 -(X 2 X 3 Si)-G 2 -S x -G 3 -(SiX 2 X 3 )] m -X 1 ; [(-Y 2 -) y/2 (X 2   3-b Si)-G ' -S-J] m [(-Y 2 -) j/2 (X 2   3-j Si)-G 2 -S x -G 3 -(SiX 2   3-k )(-Y 2 -) k/2 ] n , where the subscript h independently represents an integer from 1 to 3; subscripts j and k independently represent an integer from 0 to 3, with the condition that, j+k>0; subscript m independently represents an integer from 1 to 1000; subscript n independently represents an integer from 1 to 1000; subscript x independently represents an integer from 2 to 20; X 1  is independently chosen from a group of hydrolysable residue, containing Y 1 , -OH, -OR 1  and R 1 C(=O)O-, in which in each case R 1  independently represents any hydrocarbon fragment, obtained by removing one hydrogen atom from a hydrocarbon, containing from 1 to 20 carbon atoms. R 1  contains arylgroups and any alkyl, alkenyl, arenyl or aralkyl groups with a branched straight chain; X 2  and X 3  are independently chosen from a group containing hydrogen, R 1  and X 1 ; G 1 , G 2  and G 3  are independently chosen from a group containing hydrocarbon fragments, obtained by removing one hydrogen atom from any of the groups given above for R 1 ; J is independently chosen from a group containing R 1 C(=O)-, R 1 C(=S)-, R 1   2 P(=O)-, R 1   2 P(=S)-, R 1 S(=O)- and R 1 S(=O) 2 , where in each separate case, R 1  assumes values given above; Y 1  independently represents -O-G-(O-G-) p OR or -O-G-(O-G-) p OH, and Y 2  independently represents -O-G-(O-G-) q O-; subscript p independently represents an integer from 1 to 100; subscript q independently represents an integer from 1 to 100; G is independently chosen from a group containing hydrocarbon fragments, obtained by removing one hydrogen atom from any of the groups given above for R 1  ; and R is independently chosen from a group, where R 1  assumes values given above. Proposal is also given of a method of making the proposed binding substance, elastomer composition filled with the binding substance and a method of binding the elastomer and the filler. 
     EFFECT: design of silane binding substances in which released hydrolysable groups help improve the rubber mixture and/or properties of the end product.
