Olefin copolymer and production thereof

THIS INVENTION PROVIDES AN ETHYLENE COPOLYMER WITH A NARROW DISTRIBUTION OF ITS ATOMIC WEIGHT AND AN EXCELLENT FLOW, WHICH IS COMPOSED OF STRUCTURAL UNITS: (A) DERIVATIVES FROM ETHYLENE AND STRUCTURAL UNITS AND (B) DERIVATIVES FROM A C SUB 3 AC SUB 20 (ALPHA) -OLEFINAS, HAVING, SUCH A COPOLYMER (A) A DENSITY OF 0.85 TO 0.92 G / CM HIGH 3 , (B) A LIMITING VISCOSITY [(MU)] DETERMINED IN DECALINE AT 135 DL / G, (C) AN AVERAGE MOLECULAR WEIGHT-WEIGHT RATIO (MW) AT AVERAGE MOLECULAR WEIGHT (MN), DETERMINED BY GPC OF 1, 2 TO 4, (D) A PROPORTION OF MFR SUB 10 UNDER A LOAD OF 10-KG TO MFR SUB 2 UNDER A LOAD OF 2.16 KG FROM 8 TO 50, A 190 METALIC TRANSITIONAL COMPONENT COMPOSED OF HAFNIUM HAVING AS A LINK A MULTIDENTED COMPOUND IN WHICH AT LEAST TWO SELECTED GROUPS BETWEEN CICLOALCADIENIL GROUPS, AND SUBSTITUTED GROUPS FROM THE PREVIOUSLY ARE ALONG ANY OWN TRACKS. (B) OLEPHINE COPOLYMER ORGANOMETALLIC COMPOUND OXY-ORGAN-ALUMINUM COMPOUND.
