Abstract

THE PRESENT INVENTION PROVIDES AN ETHYLENE COPOLYMER COMPRISING CONSTITUENT UNITS (A) DERIVED FROM ETHYLENE AND CONSTITUTED UNITS (B) DERIVED FROM AN α-OLEFIN HAVING 3 TO 20 CARBON ATOMS, THE ETHYLENE COPOLYMER BEING CHARACTERIZED IN THAT(A) THE ETHYLENE COPOLYMER HAS A DENSITY (D) OF 0.86 TO 0. 95 G/CM3;(B) THE ETHYLENE COPOLYMER HAS A MFR OF 0.001 TO 50 G/10 MIN AS MEASURED AT A TEMPERATURE OF 190°C AND A LOAD OF 2.16 KG; (C) THE MELT TENSION (MT) AND MFR OF THE ETHYLENE COPOLYMER SATISFY THE RELATION LOG MT > -0.66LOG MFR + 0.6; AND (D) THE TEMPERATURE (T) AT WHICH THE EXOTHERMIC CURVE OF THE ETHYLENE COPOLYMER MEASURED BY A DIFFERENTIAL SCANNING CALORIMETER (DSC) SHOWS THE HIGHEST PEAK AND THE DENSITY (D) SATISFY THE RELATIONT T < 400D -250.(FIG.2)
