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.

Aqueous application systems for applying additives to polymeric particles, methods of preparing aqueous emulsions which include at least one processing, stabilizing or other functional polymer additive and an emulsifiable wax. Also disclosed are methods of applying additives to polymeric particles and to polymeric particles treated by such methods.

Solid form additive systems which are dispersible in aqueous media are disclosed, as are methods for preparing such additive systems. The additive systems are dry, free-flowing particulate materials that contain at least one additive component, at least one tackifying agent, and at least one surfactant.

Soft copolymer compositions in pellet form comprise said polymer pellets coated with a wax-based emulsion of N,N'-ethylenebisoleamide. The coated pellet has antiblock characteristics which allow bulk shipment and storage of soft polymers without the pellets agglomerating into an unmanageable mass. Less N,N'-ethylenebisoleamide is required to provide equivalent antiblock characteristics as compared to soft copolymer compounds in pellet from containing N,N'-ethylenebisoleamide throughout the pellet.
