A plastisol composition containing plasticizers, fillers and styrene copolymers selected from (a) styrene, alpha -methyl styrene and p-methyl styrene, and (b) 3 to 20% by weight, based on the weight of the styrene copolymers, of a comonomer selected from methacrylic acid, acrylic acid and itaconic acid, and optionally (c) a crosslinking comonomer, wherein the maximum of the molecular weight distribution of said copolymers is greater than 1 million as determined by gel permeation chromatography.
