The present invention relates to the use of optically active polymers of N-acryloyl-phenylalanine neomenthylamide as such, in crosslinked form and/or in carrier-bonded form as stationary phases for the chromatographic separation of enantiomers of lactones.

Chromatographic separation of enantiomers of lactones

Polyurethane-urea compositions are described, and, in particular, elastic polyurethane-urea fibers are described which result therefrom and which contain a dialkylsulphosuccinate as a finely dispersed or dissolved additive which considerably increases the strength of the fibers. Moreover, a method is described of producing polyurethane-urea fibers using a dialkylsulphosuccinate as an additive.
