1. A polybutene-1 resin composition substantially comprising (A) 60 to 95 weight parts of a polybutene-1 resin (A) having (i) a melt flow rate of 0.01 to 5 g/10 min, (ii) the ratio (Mw/Mn) of weight average molecular weight (Mw) to number average molecular weight (Mn) of 6 or less, and (iii) an isotactic value of 93 % or more, and (B) 40 to 5 weight parts of a polybutene-1 resin (B) having (i) a 20 times or more as large melt flow rate as that of the polybutene-1 resin (A), (ii) the ratio (Mw/Mn) of weight average molecular weight (Mw) to number average molecular weight (Mn)of 6 or less, and (iii) an isotactic value of 93 % or more. i |
