POLYMER RESINS HAVING IMPROVED BARRIER PROPERTIES AND METHODS OF MAKING SAME |
摘要 |
<p>A polymeric resin having a lower molecular weight (LMW) component and a higher molecular weight (HMW) component and the resin having a density of from about 0.955 g/cc to about 0.967 g/cc, a melt index of from about 0.5 dg/min to about 4.0 dg/min, and a zero shear viscosity of from about 3.0×103 Pa-s to about 4.0×104 Pa-s. A method comprising providing a catalyst system comprising at least one transition metal complex, an activator support, and a cocatalyst; contacting the catalyst system with an olefin under conditions suitable to form a polyolefin, wherein the polyolefin has a HMW component and a LMW component; and recovering the polyolefin, wherein the polyolefin has a melt index of from about 0.5 dg/min to about 4.0 dg/min, and a zero shear viscosity of from about 3.0×103 Pa-s to about 4.0×104 Pa-s.</p> |
