Abstract (en)
[origin: WO2011107577A2] The invention relates to zinc salts of C4-8-alkane dicarboxylic acids, which can be obtained by reacting C4-8-alkane dicarboxylic acids with surface-modified zinc oxide particles, wherein the surface-modified zinc oxide particles can be obtained by treating zinc oxide particles with organosilanes, silazanes and/or polysiloxanes and subsequently heat treating and/or UV irradiating the treated zinc oxide particles, and to the use thereof as polymerization catalysts for producing polyalkylene carbonates.
