POLYMER COMPOSITIONS FOR ROTATIONAL MOLDING APPLICATIONS
摘要
<p>A polymer having a density of from about 0.94 g/ cm3 to about 0.96 g/ cm3 and a primary structure parameter 2 (PSP2 value) of greater than about 8.5, wherein an article formed from the polymer has an environmental stress crack resistance of equal to or greater than about 1000 hours when measured in accordance with ASTM D 1693 condition A. A polymer having at least one lower molecular weight component and at least one higher molecular weight component and having a PSP2 value of equal to or greater than about 8.5, wherein an article formed from the polymer has an environmental stress crack resistance of greater than about 1000 hours when measured in accordance with ASTM D 1693 condition A.</p>
