Abstract (en)
[origin: WO2006018180A2] The invention discloses dispersions of preferably modified strontium carbonate in organic liquids, e.g. in alcohols, ketones or, in particular, methylene chloride. The dispersions can be used for producing polymers, which have a reduced double refraction or no double refraction, and are thus suited for optical applications. The powder obtained by removing the organic liquid can be surprisingly converted into a dispersion with a low amount of energy.
