1. A self-curable polymer composition containing unsaturated polyester resinsnor epoxy resins and fillers or hardening accelerators and possibly plasticizers,nlubricants, stabilizers and modifiers, characterized in that the filler is a mixture of fillersnpowders, in a total amount of 30 - 70% by mass, containing at least 15% by mass of fillersnpowders such as chalk, talc, limestone, aluminum or magnesium hydroxide, quartz dust,nsilica and up to 85% by mass of gypsum waste from flue gas desulphurization or phosphogypsum wastenfrom the production of phosphoric acid, subjected to thermal treatment and treatment with organosilicon compoundsnfrom the group of silanes, in the form of aqueous solutions or in organic solvents,nin an amount corresponding to 0.5 - 4% by mass of an organosilicon compound in relation to the mass of wastenplaster or phosphogypsum. |
