PURPOSE: Provided is a polyester based resin composition which is excellent in transparency, gas barrier properties and pinhole resistance. Also, provided is a molded product obtained from the polyester based resin composition. CONSTITUTION: The polyester based resin composition(D) comprises a polyamide resin(A) and a polyester resin(B), or a polyamide resin(A), a polyester resin(B) and a polyethylene terephthalate resin(C). It is characterized in that the polyester resin(B) is obtained by polycondensation of a dicarboxylic acid component containing 0.5 to 60 mol % of a dicarboxylic acid having a cyclic acetal skeleton and / or a diol component containing 0.5 to 60 mol % of a diol having a cyclic acetal skeleton, and that the blending proportions of the polyamide resin(A), the polyester resin(B) and the polyethylene terephthalate resin(C) are each in the range of 1 to 99% by weight, 1 to 99% by weight and 0 to 98% by weight, respectively on the basis of total sum weight of the components(A),(B) and(C). |
