Beschreibung
Zusammenfassung:	Aliphatic oligocarbonate polyol (I) with an average molecular weight (M n) of 500-10000 g/mol, formed from a polyol component containing 1-99 mol.% of diol compound (A), and at least a further aliphatic polyol, where the quantities of (A) and the further polyol are added to 100 mol.%, is new. Aliphatic oligocarbonate polyol (I) with an average molecular weight (M n) of 500-10000 g/mol, formed from a polyol component containing 1-99 mol.% of diol compound (A) of formula (OH-(X) m-(Si(R 1)(R 2)-O) n-Si(R 1)(R 2)-(X) m-OH), and at least a further aliphatic polyol, where the quantities of (A) and the further polyol are added to 100 mol.%, is new. n : 1-50; m : 1-20; R 1, R 2linear, cyclic or branched 1-20C alkyl; and (X) mcarbon-containing group with 1-20C atoms, in which the chain can be interrupted by heteroatoms such as O, S or N.
