NOVEL CATALYST SYSTEMS AND POLYMER RESINS HAVING IMPROVED BARRIER PROPERTIES |
摘要 |
A unimodal polymeric resin having a density of from about 0.946 g/ml to about 0.97 g/ml and a zero shear viscosity of from about 8×102 Pa-s to about 6×104 Pa-s. A method comprising (a) providing a catalyst system comprising a half-sandwich transition metal complex; (b) contacting the catalyst system with an olefin under conditions suitable to form a polyolefin, wherein the polyolefin is unimodal; and (c) recovering the polyolefin, wherein the polyolefin has a density of from about 0.946 g/ml to about 0.97 g/ml and a zero shear viscosity of from about 8×102 Pa-s to about 6×104 Pa-s. A unimodal polymeric resin having a density of from about 0.946 g/ml to about 0.97 g/ml and a CY-a parameter of from about 0.5 to about 0.6. |
