Title:
ポリエステル系樹脂組成物の製造方法及びポリエステル系樹脂組成物並びに成形体
Document Type and Number:
Japanese Patent JP7151122
Kind Code:
B2
Abstract:
To provide a method for manufacturing polyester-based resin composition, in which the polyester-based resin composition is provided with improved mechanical properties such as impact resistance, tear strength and tensile breaking elongation and has little deterioration in mechanical properties even when stored as a product for a long time of period.SOLUTION: There is provided a manufacturing method, in which 100 pts. mass of a polyester-based resin (X) including: an aromatic-aliphatic copolyester-based resin (A) containing a repeating unit derived from aliphatic diol and a repeating unit derived from aliphatic dicarboxylic acid and a repeating unit derived from aromatic dicarboxylic acid as main constitutional units; an aliphatic polyester-based resin (B) containing a repeating unit derived from aliphatic diol and a repeating unit derived from aliphatic dicarboxylic acid as main constitutional units; and a polyester-based resin (C) containing an aliphatic oxycarboxylic acid in a molten state at a temperature of 80°C or more and 250°C or less is mixed with 0.1 to 5 pts. mass of an aliphatic polyfunctional isocyanate compound (D).SELECTED DRAWING: None
