Abstract: The present invention relates to a process for the preparation of a readily water-redispersible polymer powder by spray drying of an aqueous polymer B dispersion, wherein the spray drying of the aqueous polymer B dispersion is effected in the presence of a polymer A, wherein polymer A has a glass transition temperature ?60° C., a weight average molecular weight Mw?1000 and ?25000 g/mol, a polydispersity index ?5 and is composed of ?5 and ?50 wt % of at least one ?,?-monoethylenically un-saturated mono- or dicarboxylic acid and/or anhydride (monomer A1), and ?50 and ?95 wt % of at least one other ethylenically un-saturated compound which is copolymerizable with the monomers A1 (monomer A2), in polymerized form, wherein the monomer amounts A1 and A2 sum up to 100 wt %.

Abstract: Styrene-acrylic dispersants for use in pigment dispersions have lower viscosities than benchmark formulations such as nitrocellulose, dimer-acid based polyamides, and thermoplastic polyurethanes, prepared under otherwise identical conditions. Lower viscosities allow for the preparation of similarly viscous dispersions and inks with the styrene-acrylics when compared to traditional dispersants, at either (a) lower solvent levels, or if solvent levels are to be maintained, (b) higher pigment and solids loadings.

Abstract: Methods for forming high molecular weight chain-extended condensation polymers are disclosed.
