Abstract (en)

[origin: WO2005000931A1] The invention relates to prepolymers (A) with terminal groups of general formula (1) -SiR<1>a(OR<2>)3-a, whereby R<1> represents an optionally halogen-substituted alkyl, cycloalkyl, alkenyl or Aryl radical having 1-10 carbon atoms; R<2> represents an alkyl radical having 1-6 carbon atoms or a omega-oxaalkyl-alkyl radical having, in total, 2-10 carbon atoms; a is a number from 0 to 2, whereby the prepolymers (A) can be obtained by reacting: 1) polyol (A1) having an average molecular weight Mn ranging from 1000 to 25000; 2) low-molecular alcohol (A2) having at least two hydroxyl groups per molecule and a molecular weight ranging from 62 to 300; 3) di- or polyisocyanate (A3), and; 4) alkoxysilane (A4), which have an isocyanate group or an isocyanate-reactive group, whereby the low-molecular alcohol (A2) and the polyol (A1) are used in a molar ratio ranging from 0.3: 1 to 7: 1.
