<p>The invention relates to a method for preparing amino alkyl(meth)acryrlates by means of transesterification from C1-C4 alkyl(meth)acrylates and amino alcohols. The transesterification is carried out in the presence of at least one distannoxane, which serves as a catalyst, of general formula (1), whereby: R represents a linear, cyclic or branched alkyl radical with 1 to 6 carbon atoms, and represents a phenyl radical, whereby the R s can be identical to or different from one another; Y represents halogen, preferably C1, Br, represents pseudohalogen, preferably SCN, and represents OH, OAc or OR, whereby the Y s can be identical to or different from one another. The invention also relates to the use of the amino alkyl(meth)acrylates, which are prepared according to said method, for preparing cationic monomers.</p> |
