1. A composition comprising,(a) a polymer derived from ethylene polymer derived from at least one polar monomer with one or more ester groups, which polymerize with ethylene, and(b) a rosin ester having a hydroxyl number of seven or less, an Mz value between 2500 and 12000 and less than 800 ppm sulfur,wherein the rosin ester is obtained byesterifying a rosin andstripping off volatiles.
