    摘要: N-substituted perfluoroalkylated pyrrolidines of the formula III where RF, B, Q and q are as defined herein are prepared from diallylamine, a perfluoroalkyl iodide and an amino-reactive compound selected from the group of carboxylic acids, anhydrides, acid chlorides, oxiranes, haloalkanes, isocyanates, ureas and (meth)acrylic compounds. These compounds are useful as specialty surfactants and as oil-proofing agents for paper and textiles. Polymers derived from the (meth)acrylamides are useful to impart water, oil and grease repellency to various substrates.
