Abstract
The invention relates to polystyrene binders modified by fatty compounds. The fatty compounds used are, in particular, esters of fatty acids or fatty alcohols, more especially triglycerides of higher fatty acids, preferably natural fats and oils. They may be added to the binder in high concentrations without adversely affecting the properties of the binder. However, their addition is of advantage in regard to the wetting properties, resistance to water and, above all, hardness. Dispersion adhesives, hotmelt adhesives and sealing compounds in particular can be improved with the binders according to the invention.
