Abstract
(EN) The polyester resin according to the present invention is obtained by using a polyethylene terephthalate, a multivalent carboxylate component, and a polyhydric alcohol component. In the polyester resin, the total contained amount of at least one selected from the group consisting of structural units derived from a carboxylate having a valence of three or more and structural units derived from an alcohol having a valence of three or more is at least 1 part by mol with respect to 100 parts by mol of structural units derived from an acid component. The endothermic energy amount of the polyester resin when being heated for 30 minutes at 150°C is 0.1-10 J/g.
(FR) La résine de polyester selon la présente invention est obtenue en utilisant un polyéthylène téréphtalate, un composant carboxylate multivalent et un composant d'alcool polyhydrique. Dans la résine de polyester, la teneur totale d'au moins un élément choisi dans le groupe constitué de motifs structuraux dérivés d'un carboxylate ayant une valence de trois ou plus et de motifs structuraux dérivés d'un alcool ayant une valence de trois ou plus étant d'au moins 1 partie en moles par rapport à 100 parties en moles de motifs structuraux dérivés d'un composant acide. La quantité d'énergie endothermique de la résine de polyester lorsqu'elle est chauffée pendant 30 minutes à 150 °C est de 0,1 à 10 J/g.
(JA) 本発明のポリエステル樹脂は、ポリエチレンテレフタレートと、多価カルボン酸成分と、多価アルコール成分とを用いて得られるポリエステル樹脂であって、酸成分に由来する構成単位100モル部に対して、3価以上のカルボン酸由来の構成単位及び3価以上のアルコール由来の構成単位からなる群より選ばれる少なくとも1種を合計で1モル部以上含み、150℃で30分加熱処理した際の吸熱量が0.1~10J/gである。
