摘要:
The invention provides a process for improving the storage stability of aqueous composite-particle dispersions and of aqueous formulations comprising them.
摘要:
The present invention provides for the use of an aqueous dispersion of particles composed of polymer and finely divided inorganic solid (aqueous composite-particle dispersion) as a binder in elastic coatings, such as paints, more particularly exterior architectural paints, comprising preparing the aqueous composite-particle dispersion by dispersely distributing ethylenically unsaturated monomers in an aqueous medium and carrying out polymerization by means of at least one free-radical polymerization initiator in the presence of at least one dispersely distributed, finely divided inorganic solid having an average particle diameter ≦100 nm and at least one dispersant by the method of free-radically aqueous emulsion polymerization, and using as ethylenically unsaturated monomers a monomer mixture which comprises ethylenically unsaturated monomers A and optionally 0% to ≦10% by weight of an ethylenically unsaturated monomer B containing an epoxide group (epoxide monomer).
摘要:
The present invention relates to polymer dispersions which comprise highly branched polycarbonates, to a process for preparing them, and to their use.
摘要:
A process for preparing an aqueous dispersion of particles composed of addition polymer and finely divided inorganic solid (composite particles), in which process ethylenically unsaturated monomers are dispersely distributed in aqueous medium and polymerized by the method of free-radical aqueous emulsion polymerization by means of at least one free-radical polymerization initiator in the presence of at least one dispersely distributed, finely divided inorganic solid and at least one dispersant, which comprises using a monomer mixture comprising >0 and ≦10% by weight of at least one ethylenically unsaturated monomer containing an epoxide group.
