Title:
ALIPHATIC-AROMATIC POLYESTER COMPOSITION AND METHOD FOR PRODUCING ALIPHATIC-AROMATIC POLYESTER COMPOSITION
Document Type and Number:
Japanese Patent JP2022142501
Kind Code:
A
Abstract:
To provide an aliphatic-aromatic polyester composition having a high degree of crystallinity by improving deficiency of crystallization of conventional aliphatic-aromatic polyester.SOLUTION: Provided is an aliphatic-aromatic polyester composition comprising aliphatic-aromatic polyester and a nucleating agent. The aliphatic-aromatic polyester has an aliphatic diol unit, an aliphatic dicarboxylic acid unit, and an aromatic dicarboxylic acid unit. The nucleating agent comprises one or more compounds selected from the group consisting of fatty acid metal salts, phosphates, aromatic phosphonates, polyhydric alcohols, fatty amides, and copolymers of olefins and maleic acid. The composition comprises 0.01 to 100 pts.mass of the nucleating agent relative to 100 pts.mass of the aliphatic-aromatic polyester.SELECTED DRAWING: None
