description PROBLEM TO BE SOLVED: To obtain an isosorbide-containing polyester which has superior resin quality responding to the market needs by an efficient and economical continuous method.SOLUTION: The present invention relates a polyester produced by a method which comprises the steps of: (a) obtaining a homogeneous aqueous solution of isosorbide; (b) supplying the homogeneous aqueous solution in the step (a) to a reactor; (c) supplying glycol (which may contain or may not contain isosorbide) and a dicarboxylic acid into the aqueous solution in the step (a) or the reactor in the step (b) before, during and/or after the step (b); (d) esterifying the reactor contents at a temperatures and a pressure enough to perform esterification and optionally in the presence of a suitable catalyst; (e) forming a prepolymer; and (f)producing a polyester by polycondensing the prepolymer at a temperatures and a pressure enough to perform polycondensation in the presence of a suitable catalyst. 【課題】効率的かつ経済的な連続法により、市場の要請に応えた優良な樹脂品質を有するイソソルビド含有ポリエステルを得る。【解決手段】本発明は、(a)イソソルビドの均質水溶液を入手し;(b)工程(a)の均質水溶液を反応器に供給し;(c)グリコール(イソソルビドを含んでも含まなくてもよい)及びジカルボン酸を、工程(a)の水溶液中に、又は工程(b)の反応器中に工程(b)の前、間及び/若しくは後に供給し;(d)エステル化を行うのに充分な温度及び圧力において且つ場合によっては適当な触媒の存在下で反応器内容物をエステル化し;(e)プレポリマーを生成せしめ;そして(f)重縮合を行ってポリエステルを形成するのに充分な温度及び圧力において適当な触媒の存在下で前記プレポリマーを重縮合することによって製造されるポリエステルに関する。【選択図】なし
