Abstract:
1. A modified polypropylene which is a polypropylene having a value of racemic diad fraction [r] of 0.51 to 0.88, determined by 13 C-NMR analysis, and weight-average molecular weight (Mw) of 5,000 to 400,000, and grafted with units represented by the general formula (1): General formula (1) (wherein, R 1 is H or an alkyl group of 1 to 10 carbon atoms; R 2 is OR 4 , or a halogen selected from the group consisting of Cl, Br, F and I, or N(R 1 ) 2 or R 5 —N(R 1 ) 2 group; R 3 is H or —COR 2 group; R “n” is 1 to 500, wherein totaled number is 2 to 500, when there are 2 or more units represented by the general formula (1) in one polypropylene molecule).
