Abstract: The invention discloses dispersions of preferably modified strontium carbonate in organic liquids, for example in alcohols, ketones or particularly methylene chloride. The dispersions are usable for the preparation of polymers which have reduced birefringence or no birefringence and are therefore suitable for optical applications. The powder obtainable after the removal of the organic liquid can surprisingly be converted back to a dispersion with little energy.
