摘要： This invention relates to silanes of the general formulaR.sub.n Si(OCR.sub.2.sup.1 COZR).sub.4-nwhere R represents the same or different monovalent hydrocarbon radicals or substituted monovalent hydrocarbon radicals, R.sup.1 is hydrogen or the same as R, Z is oxygen or the group ##STR1## where R.sup.1 is the same as above, n is 0 or 1 and oligomers thereof. These silanes are prepared by reacting silanes of the general formulaR.sub.n SiX.sub.4-nwhere R and n are the same as above and X represents the same or different hydrolyzable atoms or condensable groups other than RCOCR.sub.2.sup.1 CO 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.

摘要翻译：本发明涉及通式RnSi（OCR21COZR）4-n的硅烷，其中R表示相同或不同的一价烃基或取代的一价烃基，R 1为氢或与R相同，Z为氧或基团其中R 1与上述相同，n为0或1，及其低聚物。这些硅烷通过使通式为RnSiX4-n的硅烷与其中R和n与上述相同并且X代表与RCOCR21CO基以外的相同或不同的可水解原子或可缩合基团与α-羟基羧酸酯或酰胺反应来制备。每分子具有至少三个可缩合基团的硅烷可以与含有末端可缩合基团的二有机聚硅氧烷和至少一种另外的物质混合以制备在无水条件下储存稳定但在室温下暴露于水分时交联的组合物形成弹性体。
