Abstract: 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.

Abstract: 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.

Abstract: Fluorine-containing compositions for treating substrates to render them oil-, water- and soll-repellant, comprising a fluorine-containing acrylic copolymer and a fluorine-free poly(meth)acrylate.

Abstract: The invention relates to chiral polymers which are bonded to a support and have improved properties, a process for the preparation of these materials and their use as chiral stationary phases in the chromatograhic separation of optical isomers, in particular of racemates into their enantiomers.
