Abstract
Emulsion delivery systems for applying anti-stick additives to polymer particles, provide free-flowing particles of polymers or polymer blends, that without the anti-stick additives tend to agglomerate. The agglomeration presents storage and handling difficulties. The anti-stick additives are selected from the group consisting of primary amides, secondary amides, ethylene bisamides, waxes, talc and silica.
