Document Type and Number:
Japanese Patent JP6650414
Kind Code:
B2
Abstract:
It is an object to provide a polyester resin composition and a formed article containing the polyester resin composition that make it possible to improve thermal resistance, which is a drawback of polylactic acids, and suppress burr formation, which is a drawback of poly(3-hydroxyalkanoates). The polyester resin composition includes: a polylactic acid (A); a poly(3-hydroxyalkanoate) (B); pentaerythritol (C); and a silicate (D). In the polyester resin composition, an amount of the polylactic acid (A) is not less than 55 parts by weight and not more than 75 parts by weight, and an amount of the poly(3-hydroxyalkanoate) (B) is not less than 25 parts by weight and not more than 45 parts by weight, with respect to 100 parts by weight of a total amount of the polylactic acid (A) and the poly(3-hydroxyalkanoate) (B); an amount of the pentaerythritol (C) is not less than 0.05 parts by weight and not more than 20 parts by weight with respect to 100 parts by weight of the total amount of the polylactic acid (A) and the poly(3-hydroxyalkanoate) (B); and an amount of the silicate (D) is not less than 10 parts by weight and not more than 40 parts by weight with respect to 100 parts by weight of the total amount of the polylactic acid (A) and the poly(3-hydroxyalkanoate) (B).
