An enantioselective process for the preparation of the (S)-enantiomer of an optically active cyanohydrin by reaction of an aldehyde or of a ketone with a cyanide group donor, in which the aldehyde or the ketone is reacted with a cyanide group donor in an organic diluent in the presence of a recombinant (S)-hydroxynitrile lyase from and the (S)-cyanohydrin formed is isolated from the reaction mixture.

Copolymers which are composed essentially of the structural elements ##STR1## and, if necessary, ##STR2## The copolymers can be employed as dispersing agents for inorganic or organic substances, especially as a plasticiser for hydraulic binders.

Copolymers based on maleic acid derivatives and vinyl monomers, their

Use of salts of water-soluble naphthalenesulfonic acid formaldehyde condensates having a molar formaldehyde/naphthalenesulfonic acid ratio of 1.2:1 to 3:1 and an intrinsic viscosity of 0.01 to 0.15 dl/g, as an additive to inorganic binders for improving the flowability, and a structural material prepared using binders modified in this manner.
