| titleOfInvention | Aromatic polyester resin moldings and process for production thereof |
| abstract | An aromatic polyester resin molded product, including: a matrix of 99 - 70 wt. parts of an aromatic polyester resin, and a disperse phase of 1 - 30 wt. parts (providing a total of 100 wt. parts together with the aromatic polyester resin) of a polyglycolic acid resin present in the matrix, wherein the molded product exhibits an oxygen permeability in its thickness direction which is in a range of 55 - 85 % of a minimum gas permeability P 0 determined by formula (1) below (Nielsen's theoretical formula): P0=P1*phi1/(1+ (L/2)*phi2)...(1), wherein L denotes a longer axis of the polyglycolic acid resin disperse phase; W denotes a shorter axis (thickness) of the polyglycolic acid resin disperse phase; P1 denotes an oxygen permeability of the aromatic polyester resin in an oriented and crystallized state; phi1 denotes a volumetric fraction of the aromatic polyester resin; and phi2 denotes a volumetric fraction of the polyglycolic acid resin. The molded product can be produced by subjecting a primarily molded product of a prescribed composition to stretching and heat-treatment. As a result, the aromatic polyester resin molded product formed by adding a relatively small amount of polyglycolic acid resin is provided with an improved gas-barrier property while utilizing the effect of the added polyglycolic acid resin to the utmost. |
