ABSTRACT OF THE DISCLOSURE Certain N,N'-ethylenebisamides and N,N' diadipamides added to ethylene/vinyl acetate dipolymers, terpolymers with carbon monoxide, copolymers of ethylene with methacrylic acid, and copolymers of ethylene with methyl methacrylate remarkably reduce the tendency of polymer pellets to block. Free-flowing copolymer pellets can be handled without blocking and moved more quickly through the packing equipment and can be stored for extended periods without blocking. Copolymer pellets containing these additives can be packed into large containers and shipped without blocking. The preferred additive is N,N'-ethylenebis- oleamide.
