摘要:
The instant invention provides a polyolefin composition suitable for sealant applications, sealant compositions, method of producing the same, and films and multilayer structures made therefrom. The polyolefin composition suitable for sealant applications according to the present invention comprises: an ethylene/α-olefin interpolymer composition having a Comonomer Distribution Constant (CDC) in the range of from 40 to 110, vinyl unsaturation of less than 0.1 vinyls per one thousand carbon atoms present in the backbone of the ethylene-based polymer composition; a zero shear viscosity ratio (ZSVR) in the range of from 1.01 to 2.0; a density in the range of from 0.908 to 0.922 g/cm3, a melt index (I2 at 190° C./2.16 kg) in the range of from 0.5 to 5.0 g/10 minutes, a molecular weight distribution (defined as the weight average molecular weight divided by the number average molecular weight, Mw/Mn) in the range of from 2.0 to 4.0, and tan delta at 0.1 radian/second, determined at 190° C., in the range of from 5 to 50.
