| abstract | A polyester containing 50 mol% or more of terephthalic acid units with respect to the total of dicarboxylic acid units and 50 mol% or more of ethylene glycol units with respect to the total of diol units, wherein the polyester is a cobalt compound (M ), At least one phosphorus compound (P) selected from the group consisting of phosphoric acid, phosphorous acid, organic phosphonic acid and esters thereof, and polyvalent carboxylic acid (X) having an α, β-dicarboxylic acid unit In the presence, it is formed by polycondensation of dicarboxylic acid and diol, and the addition amount of cobalt compound (M) with respect to 100 parts by mass of dicarboxylic acid is 0.0005 to 0.05 parts by mass in terms of cobalt element, The molar ratio (P / M) of the phosphorus atom in the phosphorus compound (P) to the cobalt atom in the cobalt compound (M) is 0.01 to 10 The polyester has a polyvalent carboxylic acid (X) molar ratio (X / M) of 0.01 to 10 with respect to cobalt atoms in the cobalt compound (M). Such a polyester has a good color tone, and a molded product obtained using the polyester has high transparency and excellent impact resistance. |
