Abstract:
A process for producing modified propylene polymers by subjecting a polypropylene homopolymer satisfying the requirements (a) to (e): (a) mmmm = 20 to 60 mole%, (b) [rrrr/(1-mmmm)] 2.5 mole%, (d) mm x rr/(mr) C-NMR spectroscopy is 55 to 90 mole% to modification with a radical initiator and an organic acid; modified propylene polymers obtained by the process; and adhesive compositions containing the modified propylene polymers. The modified propylene polymers can impart high adhesiveness, high strength, and softness to polyolefins and so on and give sealants having high adhesiveness or polyolefins improved in the compatibility with inorganic fillers or the like, and are useful particularly as resins for hot-melt adhesives.
