Patent ID: 6909018

Claim:
A reaction product obtained by a) epoxidation of a reactive polyalkene of the formula (III) where R 1 , R 2 , R 3 and R 4 , independently of one another, are each hydrogen or an unsubstituted or substituted, saturated or mono- or polyunsaturated aliphatic radical having a number-average molecular weight of up to 40000, at least one of the radicals R 1 to R 4 having a number average molecular weight of from 150 to 40000, to form an epoxide of the formula (IV) b) reaction of the epoxide of formula (IV) with a nitrogen compound of the formula (V) where R 5 and R 6 , independently of one another, are each hydrogen, alkyl, cycloalkyl, hydroxyalkyl, aminoalkyl, alkenyl, alkynyl, aryl, arylalkyl, alkylaryl, hetaryl or an alkyleneimine radical of the formula (II) where Alk is a straight-chain or branched alkylene, m is an integer from 0 to 10, and R 7 and R 8 , independently of one another, are each hydrogen, alkyl, cycloalkyl, hydroxyalkyl, aminoalkyl, alkenyl, alkynyl, aryl, arylalkyl, alkylaryl or hetaryl or, together with the nitrogen atom to which they are bonded, form a heterocyclic structure, or R 5 and R 6 , together with the nitrogen atom to which they are bonded, form a heterocyclic structure, it being possible for each of the radicals R 5 , R 6 , R 7 and R 8 to be substituted by further alkyl radicals carrying hydroxyl or amino groups, to form a reaction mixture comprising an amino alcohol of the formula (VI) and c) catalytic dehydration of the amino alcohol of formula (VI) and hydrogenation of the dehydrated product.
