Abstract
Plastisol compositions based on vinyl chloride/vinyl acetate copolymers produced by suspension polymerization have a low viscosity, even with low polymer-to-plasticizer ratios, so that they may be used for plastisol formulations suitable for airless spraying. The compositions are stable in storage and show good gelation properties. Coatings based on these plastisols have a good noise-damping effect, even with high vinyl acetate contents.
