ETHYLENE/ALPHA-OLEFIN COPOLYMER MADE WITH A NON-SINGLE-SITE/SINGLE-SITE CATALYST COMBINATION, ITS PREPARATION AND USE
摘要
<p>An ethylene/alpha-olefin copolymer comprising a component produced by a non-single-site polymerization catalyst and a component produced by a single-site polymerization catalyst, its preparation and use are described. The copolymer has an alpha-olefin content of 5 to 20 percent by weight and shows at least two CRYSTAF peak temperatures differing by at least 15° C. and/or at least two DSC melting peak temperatures differing by at least 15° C.</p>
