Rudloff, Jan Pretula, Julia Antonietti, Markus Kaluzynski, Krzysztof Double-Hydrophilic Block Copolymers with Monophosphate Ester Moieties as Crystal Growth Modifiers of CaCO<sub>3</sub> 2002-03-01 2017-11-10T08:48:35Z 2017-11-10T08:48:35Z terms-of-use Rudloff, Jan Antonietti, Markus Pretula, Julia eng Kaluzynski, Krzysztof Cölfen, Helmut Cölfen, Helmut The synthesis of double-hydrophilic block copolymers with a poly(ethylene glycol) block (PEG) and a block with pendant monophosphate ester groups based on a hydroxylated polybutadiene block (poly[2-(2-hydroxy ethyl)ethylene] (PHEE) with variable degrees of phosphate substitution (up to 40%) is described. It is shown that these block copolymers are very efficient scale inhibitors for CaCO<sub>3</sub>. The efficiency of these polymers is compared with block copolymers with an ionic block based on phosphorylated polyglycidol (PGL) with phosphorylation degrees up to 100%. The phosphorylated polyglycidols were also used to modify the morphology of CaCO<sub>3</sub> crystals. Instead of the typical rhombohedral calcite single crystals, superstructures of nanometer-sized particles are formed in the presence of these block copolymers when two different techniques were used: the fast double-jet technique and the slow Kitano-method. In the double-jet method, only spherical superstructures are obtained, whereas for the slower growth region covered by the Kitano method, complex cone-like or flower-like superstructures are formed.
