Abstract (en)
[origin: WO2008068223A1] Solid dispersions suitable for filter aids and made of thermoplastic polymers and a cross-linked non-water soluble polymer, wherein the solid dispersions consist of 20 to 95% by weight of at least one thermoplastic polymer (component A) and 5 to 80% by weight of at least one cross-linked non-water soluble polymer from the group consisting of homopolymers of N-vinyl formamide, N-vinyl caprolactam, N-vinyl piperidone, N-vinyl pyridines, N-vinyl imidazoles, styrene monomers, acrylates and methyl acrylates and copolymers of basic N-vinyl compounds, styrene monomers, acrylates and methyl acrylates (component B).
