Abstract:
1. A polypropylene resin, obtained by melt mixing a linear polypropylene resin, a radical polymerization initiator and a conjugated diene compound, wherein said polypropylene resin has a melt flow rate of more than 50 g/10 min and not more than 250 g/10 min as measured at 230° C. under a load of 2.16 kg; a melt tension at 200° C. of not less than 0.3 cN; and a loss tangent, tan δ, of not more than 6.0, the loss tangent being a ratio of loss modulus to storage modulus at an angular frequency of 1 rad/s in dynamic viscoelasticity measurement at 200° C.
