Abstract
A plastisol composition based on styrene copolymers, plasticizers and inorganic fillers contains, as styrene copolymers, copolymers which can be produced by emulsion polymerization and contain a) styrene and/or .alpha.-methyl styrene and/or p-methyl styrene and b) 3 to 20 wt.-% (relative to the copolymer) methacrylic acid and/or acrylic acid and/or itaconic acid. To increase the abrasion resistance, further crosslinkers or strengtheners can be added. The plastisols are suitable for use in motor vehicle construction as underseal material, as an adhesive for hood lining, as a compound for grille protection or as a spot-welding paste, and in the packaging products industry as a sealing compound for container closures or as a seam seal or as a flange-joint adhesive for tin cans.
