Abstract: Particulate styrene polymers which contain a blowing agent and are surface-coated with from 0.05 to 1% by weight of an ester. The coating agent is a hydroxycarboxylic acid ester, or an ester of a carboxylic acid with an oxyalkylated alcohol; tristearyl citrate is a preferred ester. The styrene polymers can be used to produce foam moldings, with short mold dwell times and good welding of the foam particles.
