Title:
MASTER BATCH, AROMATIC POLYESTER RESIN COMPOSITION, MOLDING AND METHOD FOR PRODUCING THESE
Document Type and Number:
Japanese Patent JP2022079922
Kind Code:
A
Abstract:
To provide a film composed of an aromatic polyester resin composition containing at least PBT resin, the aromatic polyester resin composition, and a method for producing the film, wherein it is possible to prevent a pressure rise in making a film from the resin composition while preventing the occurrence of defects in the film, and to suppress the progress of degradation of resin and enable stable film formation; and to further provide a master batch that can give the resin composition and a method for producing the same.SOLUTION: The present invention provides a master batch that contains, relative to 100 pts.mass of an aromatic polyester resin with an inherent viscosity of 0.5 or more to less than 0.9, less than 15 pts.mass of fine particles with an average particle size of 0.5-10 μm, and a method for producing the same. There are also provided an aromatic polyester resin composition for films including the master batch, and a method for producing films.SELECTED DRAWING: None
