Abstract: The purpose of the present invention is to provide a polar-group-containing propylene-type wax having excellent properties including a low melting point. A modified propylene-(α-olefin) copolymer (A) according to the present invention is produced by grafting at least one compound selected from an unsaturated carboxylic acid, a derivative of the unsaturated carboxylic acid and an unsaturated sulfonic acid salt onto a propylene-(α-olefin) copolymer (A1) and has an acid value of 1 to 100 KOHmg/g, wherein the propylene-(α-olefin) copolymer (A1) comprises 60 to 95 mol % of a propylene-derived constituent unit (a) and 5 to 40 mol % of a constituent unit (b) derived from an α-olefin having 4 or more carbon atoms, and satisfies the specific requirements (i) to (iii).
