    • Blends comprising an ethylene based polymer having a glass transition temperature lower than or equal to 20° C. and cycloolefin polymer are prepared. The ethylene based polymer preferably comprises at least 60 weight % of ethylene, relative to the weight of the polymer and polar monomers selected from the group of carboxylic acids, alkyl acrylates and vinyl acetates. It is preferably 0.01 to about 99.5% neutralized with metal ions selected from sodium, potassium, zinc, calcium, magnesium, lithium, aluminum, nickel, and chromium. The cycloolefin polymer is preferably an ethylene-norbornene copolymer. The invention also relates to the applications of such blends to improved impact resistant molded articles.
