SILANES AND CURABLE COMPOSITIONS INCLUDING THE MENTIONED SILANES Russian patent published in 2021 - IPC C07F7/18 C08K5/5419 C08L83/04 

FIELD: chemistry.

SUBSTANCE: invention relates to silane compounds having ester groups. A silane compound with the general formula SiR¹_n(R²)_4-n (I) is proposed, where R¹ is independently selected from groups having the formula -OCH(CH₂COOR³)COXR³ (II), X is O, each R³ is independently selected from unsubstituted linear alkyl groups having 1-22 carbon atoms, each R² is independently selected from monovalent alkenyl, alkyl or aryl groups having 1-18 carbon atoms, and n has the value of 2, 3 or 4. A method for producing the mentioned silane compound, a crosslinking agent and a curable composition based on the mentioned silane compound, and the use of the silane compound and the curable composition are also proposed.

EFFECT: proposed silane compounds can be used as neutral crosslinking agents in curable compositions based on polyorganosiloxanes, providing acceptable crosslinking properties without adversely affecting the storage of the curable compositions.
