ABSTRACT A composition comprising in intimate admixture (a) at least one copolymer of from 2 to 35 weight percent acrylic or methacrylic acid and 98 to 65 weight percent ethylene having a melt flow volume of from 0.01 to 50 dg/min; and being preparedby interpolymerization at a reactor temperature and pressure above its two-phasetransition zone, and, (b) from 0.05 to 2 percent, by weight of the composition, of at least one secondary fatty acid amide of the formula R7-CO-NH-R8 wherein R7 is a saturated alkyl group having from 11 to 25 carbon atoms and R8 is a mono- olefinically unsaturated alkyl group having from 18 to 24 carbon atoms. The polymers are preferably prepared at a temperature and pressure above the two-phase transition zone. The compositions are useful for making films and in extrusion coating of various substrates.
