Abstract
Novel copolymers comprise ethylene and alpha olefins having from 3 to 10 carbon atoms and which have The copolymers are particularly useful in film applications showing an excellent balance of processing, optical and mechanical properties. The novel polymers may suitably be prepared in the gas phase in the presence of metallocene complexes.
