- 1. An aliphatic polyester resin composition comprising: a polyhydroxyalkanoate (A); pentaerythritol (B); and a filler (C),
wherein the polyhydroxyalkanoate (A) is at least one selected from the group consisting of poly(3-hydroxybutyrate-co-3-hydroxyvalerate), poly(3-hydroxybutyrate-co-3-hydroxyhexanoate), and poly(3-hydroxybutyrate-co-4-hydroxybutyrate), the filler (C) is an inorganic filler, an organic filler or a combination thereof, wherein the inorganic filler is at least one selected from the group consisting of silicate, carbonate, sulfate, and nitride, and the organic filler is made from at least one selected from a woody material and an organic fiber, an amount of the filler (C) is from 10 to 100 parts by weight based on 100 parts by weight of the polyhydroxyalkanoate (A), and an amount of the pentaerythritol (B) is from 0.3 to 5 parts by weight based on 100 parts by weight of the polyhydroxyalkanoate (A).
- 13. An aliphatic polyester resin composition comprising: polyhydroxyalkanoate (A); a crystal nucleating agent comprising pentaerythritol (B); and a filler (C),
wherein the polyhydroxyalkanoate (A) is at least one selected from the group consisting of poly(3-hydroxybutyrate-co-3-hydroxyvalerate), poly(3-hydroxybutyrate-co-3-hydroxyhexanoate), and poly(3-hydroxybutyrate-co-4-hydroxybutyrate), the filler (C) is an inorganic filler, an organic filler or a combination thereof, wherein the inorganic filler is at least one selected from the group consisting of silicate, carbonate, sulfate, and nitride, and the organic filler is made from at least one selected from a woody material and an organic fiber, an amount of the filler (C) is from 10 to 100 parts by weight based on 100 parts by weight of the polyhydroxyalkanoate (A), and an amount of the pentaerythritol (B) is from 0.3 to 5 parts by weight based on 100 parts by weight of the polyhydroxyalkanoate (A).
