See full text

A method for reducing the hygroscopicity of a material (M) including calcium carbonate may include treating the calcium carbonate with at least one homopolymer grinding assistant (P) which is neutralized in a particular way. A method for producing such a material (M) including calcium carbonate may include treating the calcium carbonate with at least one homopolymer grinding assistant (P) to provide such a material (M), which is then of reduced hygroscopicity. Such a calcium carbonate may be used as a filler in polymeric plastics.
