摘要： Disclosed are compositions which include an ethylene polymer derived from at least one polar monomer with one or more ester groups, and a rosin ester. The rosin ester can have a low hydroxyl number (e.g., a hydroxyl number seven or less), a low acid number (e.g., an acid number of ten or less), a relatively low PAN number (e.g., a PAN number less than twenty-five), a relatively high third moment or third power average molecular weight (Mz), (e.g., an Mz value in between 2500 and 12000 g/mol), a low sulfur content (e.g., a sulfur content lower than 600 ppm prior to antioxidant addition) or combinations thereof. The compositions can exhibit a high heat stress resistance (e.g., a heat stress pass temperature value higher than 52° C. or in between 48° C. and 60° C.) and/or improved viscosity stability and/or color stability upon thermal aging and/or improved compatibility.
