Abstract

Foreliggende oppfinnelse vedrører generelt anven- delse av nye, hydrofobt assosierende polyelektro- lyttsammensetninger som koagulanter. Anvendelse av nevnte nye, hydrofobt assosierende polyelektrolytt- sammensetninger for awanning av kullavgang, ren- kullprodukter, mineraloppslemminger, samt klaring av vann inneholdt i kullavfalloppslemminger er ; vist. Disse polyelektrolyttsammensetningene er ; hydrofobt assosierende kopolymere bestående av ! diallyldimetylammoniumklorid (DADMAC) og et vinyl- i trialkoksysilan, fortrinnsvis vinyltrimetoksysilan (VTMS).
