An aromatic polyester resin composition, comprising: a melt-kneaded product of 99-70 weight parts of an aromatic polyester resin and 1-30 wt. parts (providing a total of 100 wt. parts together with the aromatic polyester resin) of a polyglycolic acid resin, wherein the composition is characterized by a transesterification rate C.sub.TE (%) of 20-60% determined by formula (1) below based on a peak integration ratio of methylene group in polyglycolic acid appearing at .sigma.4.87 ppm with reference to tetramethylsilane according to .sup.1H-NMR measurement: C.sub.TE (%)=(1-I(B)/I(A)).times.100 (1), wherein I (A): a peak integration ratio of the methylene group of the polyglycolic acid main chain with respect to the alkylene group of the aromatic polyester main chain calculated from the components weight ratio; and I (B): a peak integration ratio of the methylene group of polyglycolic acid main chain to the alkylene group of the aromatic polyester main chain in the resin composition. As a result, the aromatic polyester resin composition obtained by adding a relatively small amount of polyglycolic acid resin is provided with a good harmony of gas-barrier property and transparency.       Recently Added Patents Wave ripple panel Methods and systems for assessing the quality of automatically generated text Cantilever skidding system on a drilling rig Method and apparatus for employing rules to filter streaming data Cut point detection system and short recognition system using the same, cut point detection method and cut point detection program System and method for flexible spread participation Method and apparatus for identifying an order in a network   Randomly Featured Patents Lead alloy used for sliding bearing Elevating, reversible self-steering suspension system Electrical connector Switch device for vehicle Wireless MR receiving coil system Method and system for measuring leadership effectiveness Method and apparatus for presenting a user interface Portable communication terminal Ceiling fan Optical reading and recording device containing a radiation source which has a substantially constant mean heat dissipation during reading and recording © 2006-2008 PatentGenius.
