ABSTRACT:
The present invention relates to butene-1 homopolymers, or copolymers containing up to 20% by weight of alpha olefins having from 2 to 10 carbon atoms other than butene-1, characterized by the following properties: (i) a Molecular Weight Distribution (MWD) in terms of Mw/Mn, measured by GPC analysis according to the method specified, of lower than 6; and (ii) a melt strength (measured according to the method specified below) higher than 2.8.
