    摘要: Silyated polyurethanes can be manufactured by (A) converting (i) at least one polyol compound A with a molecular weight of 500-20,000 Dalton, in particular 4000-10,000 Dalton, (ii) with a dihalogenide to a polyol compound B with a molecular weight of 4000-40,000 Dalton, in particular 8000-20,000 Dalton, and subsequent (B) conversion of this polyol B with one or more isocyanatosilanes of formula (1): OCN—R—Si—(R1)m(-OR2)3-m where m is 0.1 or 2, each R2 is an alkyl radical with 1 to 4 carbon atoms, each R1 is an alkyl radical with 1 to 4 carbon atoms and R is a difunctional organic pump. These silylated polyurethanes are suited to use as adhesives, sealant or coating agent in preparations containing one or more such silylated polyurethane.
