ABSTRACT:
An ethylenic copolymer composition including an ethylenic copolymer having Mw/Mn of 1.5 to 4, Mw of 3,000 to 1,000,000, and a resin density of 0.85 to 0.95 g/cm3. The relationship between the half width at the half maximum [W/2] of the Gaussian distribution curve, and the average, n, of short-chain branches in the copolymer satisfies the equation,in-line-formulae description="In-line Formulae" end="lead"?0.704+0.147n=W/2=−0.055+0.577n.in-line-formulae description="In-line Formulae" end="tail"?The ethylenic copolymer composition also includes an ethylenic copolymer having an Mw of 3,000 to 1,000,000 and a resin density of 0.85 to 0.95 g/cm3.
