Abstract:
The present invention relates to a process for producing an aqueous suspension of precipitated calcium carbonate, an aqueous suspension of precipitated calcium carbonate and a precipitated calcium carbonate obtained by the process, a product comprising the aqueous suspension of precipitated calcium carbonate or the precipitated calcium carbonate as well as its use.

Claim (Index 1):
A process for producing an aqueous suspension of precipitated calcium carbonate comprising the steps of:\n i) providing a calcium oxide containing material; ii) providing at least one copolymer of the following formula (I) wherein x, y and z are present in blocks, alternating or randomly; x is >0 and at least one of y or z is >0 and the sum of x+y+z is \u2264150; R 1  represents hydrogen or a sulphonic functional group; R 2  represents a heteroatom, optionally substituted with an alkyl group, an alkenyl group, an heteroaryl group and/or a polyalkoxylated group; R 3  and R 4  are independently from each other a hydroxyl group, (O \u2212 M + ) with M +  being a monovalent, divalent or trivalent cation, an O-alkyl group comprising from 1 to 20 carbon atoms, an N-alkyl group comprising from 1 to 20 carbon atoms and/or a polyalkoxylated group; iii) preparing a milk of lime by mixing water, the calcium oxide containing material of step i), and the at least one copolymer of step ii) to obtain a milk of lime, wherein the calcium oxide containing material and the water are mixed in a weight ratio from 1:1 to 1:12; and iv) carbonating the milk of lime obtained in step iii) to form an aqueous suspension of precipitated calcium carbonate.
