Storage stable particulate mixture of polysaccharides and/or polysaccharide derivatives and at least a synthetic polymer, process for their preparation and use in building compositions

摘要

Particle compositions (I) based on polysaccharides and/or polysaccharide derivatives (II), at least one synthetic polymer (III) and optionally other auxiliary substances, in which (a) the particles contain several solid phases and (b) the solid phase of the polymer (III) is contained in the solid phase of (II). An independent claim is also included for a method for the production of (I) by (A) mixing moist (II) (water content = 30-80 wt%) with 0.01-25 wt% undissolved (III) (based on dry II), (B) processing the mixture in a homogeniser, optionally with the addition of water and (C) working up the resulting material by milling and drying, or by drying and then milling, or by subjecting it to a mill-drying process.
