Abstract
Novel copolymers having a density (D) in the range 0.895-0.910 g/cm, a melt index MI(2.16 kg, 190° C.) in the range of 0.01-6 g/10 min, a Compositional Distribution Branch Index (CDBI) in the range 55-85%, and a sealing initiation temperature (SIT) and density (D) satisfying the relationship SIT≤(A×D)−B wherein A is 800° C.×cm/g and B is 650° C., wherein the SIT (° C.) is determined on a 70 μm film at 0.5N/15 mm and D Is in units of g/cmare disclosed. The copolymers may be suitably prepared by use of metallocene catalyst systems and may be used in film applications, in particular as sealing layers for packaging applications.
