SILANES AND COMPOSITIONS PREPARED BY MAKING USE OF THE SILANES |
摘要 |
This invention relates to silanes of the general formula RnSi(OCR21COZR)4-n where R represents the same or different monovalent hydrocarbon radicals or substituted monovalent hydrocarbon radicals, R1 is hydrogen or the same as R, Z is oxygen or the group <IMAGE> where R1 is the same as above, n is 0 or 1 and oligomers thereof. These silanes are prepared by reacting silanes of the general formula RnSiX4-n where R and n are the same as above and X represents the same or different hydrolyzable atoms or condensable groups other than RCOCR21CO groups, with alpha-hydroxycarboxylic acid esters or amides. The silanes, which have at least three condensable groups per molecule, may be mixed with a diorganopolysiloxane containing terminal condensable groups and at least one additional substance to prepare compositions which are storage-stable under anhydrous conditions, but crosslink when exposed to moisture at room temperature to form elastomers. |
