ABSTRACT:
A process for the preparation of aminoalkyl (meth)acrylates by transesterification from C1–C4-alkyl (meth)acrylates and aminoalcohols is described, in which process the transesterification is carried out in the presence of at least one distannoxane of the general formula (1)whereinR=linear, cyclic or branched alkyl radical having from 1 to 6 carbon atoms, phenyl radical, and the radicals R may be identical or different from one another,Y=halogen, preferably Cl, Br; pseudo-halogen, preferably SCN; OH, OAc or OR, the radicals Y being identical or different from one another,as catalyst, and the use of the aminoalkyl (meth)acrylates prepared according to the process in the preparation of cationic monomers.
