| abstract |
The invention concerns polystyrene binders modified by fats, in particular esters of fatty acids or fatty alcohols, in particular triglycerides of higher fatty acids, preferably natural fats and oils. The fats can be added to the binder in high concentrations without impairing the binding properties. The addition of these fats is advantageous as concerns the wetting properties, waterproofness and above all hardness. In particular, dispersion adhesives, hot-melt adhesives and sealing compounds can be improved on the basis of the binders according to the invention. |
