Novel copolymers having a density (D) in the range 0.895-0.910 g/cm, a melt index MI(2.16 kg, 190&#xb0; 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&#x2264;(A&#xd7;D)&#x2212;B wherein A is 800&#xb0; C.&#xd7;cm/g and B is 650&#xb0; C., wherein the SIT (&#xb0; C.) is determined on a 70 &#x3bc;m 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.

Process for controlling the (co)polymerization of olefins in a continuous polymerization reactor wherein the olefin (co)polymerization is performed in an industrial plant reactor in the presence of a polymerization catalyst characterized in that at least one operating parameter of the plant is controlled by means of a measurement of the chain branching level (CBL) of the produced polymer.
