BINDING SUBSTANCE FOR ELASTOMER COMPOSITIONS FILLED WITH MINERALS Russian patent published in 2009 - IPC C07F7/08 C08K5/5419 C08K5/548 C08K9/06 

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-G¹-(SiX²X³)][-Y²-(X²Si-G¹-S-J)]_m-X¹; [X¹X²X³Si-G²-S_x-G³-Si(X²X³)][-Y²-(X²Si)-G²-S_x-G³-(SiX¹X²X³)]_m-X¹; [X¹X²X³Si-G²-S_x-G³-Si(X²X³)][-Y²-(X²X³Si)-G²-S_x-G³-(SiX²X³)]_m-X¹; [(-Y²-)_y/2(X² _3-bSi)-G^'-S-J]_m[(-Y²-)_j/2(X² _3-jSi)-G²-S_x-G³-(SiX² _3-k)(-Y²-)_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; X¹ is independently chosen from a group of hydrolysable residue, containing Y¹, -OH, -OR¹ and R¹C(=O)O-, in which in each case R¹ independently represents any hydrocarbon fragment, obtained by removing one hydrogen atom from a hydrocarbon, containing from 1 to 20 carbon atoms. R¹ contains arylgroups and any alkyl, alkenyl, arenyl or aralkyl groups with a branched straight chain; X² and X³ are independently chosen from a group containing hydrogen, R¹ and X¹; G¹, G² and G³ are independently chosen from a group containing hydrocarbon fragments, obtained by removing one hydrogen atom from any of the groups given above for R¹; J is independently chosen from a group containing R¹C(=O)-, R¹C(=S)-, R¹ ₂P(=O)-, R¹ ₂P(=S)-, R¹S(=O)- and R¹S(=O)₂, where in each separate case, R¹ assumes values given above; Y¹ independently represents -O-G-(O-G-)_pOR or -O-G-(O-G-)_pOH, and Y² independently represents -O-G-(O-G-)_qO-; 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 R¹ ; and R is independently chosen from a group, where R¹ 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.
