Abstract: The invention relates to the use of polyacrylic acids which contain organic terminal groups containing sulphur, comprising at least two carbon atoms, having an average molecular weight Mwof 5 000 - 30 000 g/mol and which are a t least partially neutralised by a base which is selected from the group of alkali hydroxides and ammonia as auxiliary agents for wet grinding of calciu m carbonate. The invention also relates to fine particle aqueous suspensions o f calcium carbonate which are produced by wet grinding of calcium carbonate in the presence of said polyacrylic acids.
