摘要： The present invention relates to a method for producing a modified propylene-based polymer containing modifying a propylene-based polymer by a radical initiator and an organic acid, a modified propylene-based polymer obtained by the method, and an adhesive composition containing the modified propylene-based polymer. The propylene-based polymer is a propylene homopolymer satisfying the conditions of (a) mmmm = 20 to 60 mol%, (b) [rrrr/(1-mmmm)] ≦ 0.1, (c) rmrm > 2.5 mol%, (d) mm×rr/(mr) 2 ≦ 2.0, and (e) the weight ratio (W25) of components eluted at 25°C or lower in a temperature programmed chromatography is 20 to 100% by weight, or a propylene copolymer satisfying the condition of (h) the stereoregularity index (P) obtained by 13 C-NMR measurement is 55 to 90 mol%.
The modified propylene-based polymer of the invention can make a polyolefin, etc. more adhesive, stronger, or flexible, to be useful for a high-adhesive sealant or an polyolefin with increased compatibility to an inorganic filler, etc., particularly as a resin for a hot-melt adhesive.

摘要： A crystalline higher α-olefin polymer which is obtained from a C 10 or more α-olefin and satisfies either (1) the melting point (Tm) as measured with a differential scanning calorimeter (DSC) is 20 to 100°C or (2) in an examination of spin-lattice relaxation time (T 1 ) by solid NMR analysis, a single T 1 is observed at the temperatures not lower than the melting point; and a process for producing the α-olefin polymer with a specific metallocene catalyst. The crystalline higher α-olefin polymer is excellent in low-temperature characteristics, rigidity, heat resistance, compatibility with lubricating oils, mixability with inorganic fillers, and secondary processability.
