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) wherein R=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.

Abstract: The invention relates to a printable one-component swelling paste made of an aqueous mixture of a water-soluble polymer containing carboxyl groups, and at least one multifunctional alcohol as crosslinker and optionally further additives such as thickeners, the carboxyl groups of the polymer being neutralized to 40-65 mole-%. The invention also relates to the use of the swelling paste for producing water-swellable yarns, fabrics, nonwovens, or films. After coating the swelling paste on a support, a thermal subsequent treatment is effected for the purpose of drying and crosslinking the swelling paste.
