(Log M) of a molecular weight (M), a weight average molecular weight of 100,000 to 300,000 g / mol, a molecular weight distribution (Mw / Mn) of 5 to 30, a density of 0.930 to 0.960 g / (Log M) of the molecular weight (M) is in the range of 3 to Mp (GPC curve of dw / dlog M) in the graph of the x axis and branching content of 2 to 7 carbon atoms per 1,000 carbon atoms as the y axis (Log M) of the molecular weight (M) is in the range of Mp to 5.5, and the difference between the average slope value in the range of Mp and 5.5 is not less than 2.
