    • The invention relates to hydrolyzable and polymerizable, low viscous and flexible silanes of general formula (I): B{(A)d-R'-U-R'-SiXaRb}c wherein the radicals and indices have the following meanings:B = a monovalent tetravalent straight-chained or cross-linked organic radical with at least one C=C double bond and 4 -50 carbon atoms;X = hydrogen, halogen, hydroxy, alkoxy, acyloxy, alkylcarbonyl, alkoxycarbonyl or NR"2. R = alkyl, alkenyl, aryl, alkylaryl or arylalkyl; R' = alkylene, alkenylene, arylene, arylenalkylene or alkylenarylene with respectively 0 - 10 carbon atoms, whereby said radicals can be interrupted by oxygen and sulphur atoms or by amino groups; R" = hydrogen, alkyl or aryl; U = an inorganically modified organic radical which has a siloxane, carbosilane or carbosiloxane skeleton with at least two (siloxane, carbosiloxane) silicon or germanium atoms or one (carbosilane) silicon or germanium atom and 1 -15 C atoms as well as up to 5 additional heteroatoms from the group of O, S, N; A = C(O)O, OC(O)O, C(O), O, S, C(O)NR", OC(O), NR"C(O); a = 1, 2 or 3; b = 0, 1 or 2; a + b = 3; c = 1, 2, 3 or 4; d = 0 or 1. Despite their low viscosity and flexibility, the silanes do not evaporate from the materials formulated therewith and are individually suitable or suitable when combined with other constituents for the production of scratch-resistant coatings, filling materials, adhesive materials, sealing materials, shaped bodies or embedding materials.
    • 本发明涉及水解性和可聚合的低粘度和通式(I)的柔性硅烷:{B(A)d-R'-U-R'-SiXaRb} c,式中的基团和指数具有以下含义:B = 具有至少一个C = C双键和4-50个碳原子的一价至四价直链或支链有机基团; X =氢,卤素,羟基,烷氧基,酰氧基,烷基羰基; 烷氧基羰基或NR“2,R =烷基,烯基,芳基,烷芳基或芳基烷基;. R“=亚烷基,亚烯基,亚芳基,亚芳基亚或亚烷基亚芳分别与0至10个碳原子,其中这些基团可被氧原子和硫原子或由氨基中断 R“=氢,烷基或芳基; U =具有硅氧烷,或Carbosiloxangerüst碳硅烷具有至少两个(硅氧烷碳硅氧烷)或(碳硅烷)硅或锗原子,和1至15个碳原子的无机改性的有机基团和多达5个附加 来自O,S,N组的杂原子具有; A = C(O)O,OC(O)O,C(O),O,S,C(O)NR “OC(O),NR” C(O); a = 1,2或3; b = 0,1或2; a + b = 3; c = 1,2,3或4; d = 0或1。尽管其低粘度和它的灵活性,硅烷不会从与它们配制群众蒸发,它们可单独使用或一起使用与其它组分用于生产抗划伤涂料,填充,粘合剂或密封剂,模塑 或嵌入材料。
