    • A resin modifier (C) obtained by reacting a polyolefin (A) having a group which reacts with a carbodiimide group, and a carbodiimide group-containing compound (B), wherein the content of the carbodiimide group is from 1 to 200 mmol per 100 g of the resin modifier, and a polar group-containing polymer composition (F) comprising from 1 to 30% by weight of the resin modifier (C), from 99 to 20% by weight of a polar group-containing polymer (D), and from 0 to 80% by weight of an olefin polymer (E). The modifier can provide improved low-temperature impact resistance of a polymer alloy including a polar group-containing polymer and an olefin polymer (such as polylactic acid and polypropylene), and can provide a molded article with smooth surface when the polymer alloy is molded. A polar group-containing polymer composition is also set forth.
