SILANES AND CURABLE COMPOSITIONS WHICH CONTAIN THESE SILANES AS CROSS-LINKING AGENTS Russian patent published in 2020 - IPC C07F7/18 C08L83/04 C08L83/08 C08L83/12 

FIELD: chemistry.

SUBSTANCE: present invention relates to silane, a method of producing silane and a curable composition. Disclosed is a silane of formula (1): Si(R¹)_m(R²)_n(R³)_4-(m+n), wherein each substitute R³ independently has a residue of general formula (3). Method of silane production is characterized by that molar ratio of silane to aminosilane compound is preferably from 2:1 to 30:1, particularly preferably varies from 4:1 to 15:1. Disclosed is a curable composition containing silane, polyohanosiloxane and a curing catalyst, in particular a tin compound.

EFFECT: technical result is obtaining novel silane compounds which can be used as neutral cross-linking agents in curable compositions based on polyorganosiloxanes, without adversely affecting stability of curable compositions during storage.
