Title (EN) POLYESTER INCLUDING 4-HYDROXYBUTYRATE UNITS
(FR) POLYESTER CONTENANT UNE UNITÉ 4-HYDROXYBUTYRATE
(JA) 4-ヒドロキシブチレート単位を含むポリエステル
Abstract:
(EN) In order to provide a polyhydroxyalkanoate polymer containing 4-hydroxybutyrate units and having high breaking strength and breaking elongation, the polyester according to the present invention has a weight-average molecular weight of at least 1,250,000 in terms of polystyrene as measured by gel permeation chromatography and includes at least 3-hydroxybutyrate units and 4-hydroxybutyrate units as polymerized units, the ratio of 4-hydroxybutyrate units with respect to all the monomer units being 14 mol% to 40 mol%.
(FR) L'invention fournit un polyhydroxyalcanoate comprenant une unité 4-hydroxybutyrate d'un polymère de résistance à la rupture et d'allongement à la rupture élevés. Plus précisément, l'invention concerne un polyester qui présente une masse moléculaire moyenne en poids supérieure ou égale à 1250000 selon une mesure au moyen d'une chromatographie par perméation de gel en termes de poystyrène, qui contient au moins en tant qu'unités polymère une unité 3-hydroxybutyrate et une unité 4-hydroxybutyrate, et qui est tel que la proportion d'unité 4-hydroxybutyrate par rapport à l'ensemble des unités monomère est comprise entre 14% en moles et 40% en moles.
(JA) 破壊強度が高く、破壊伸びが高い高分子量体の4-ヒドロキシブチレート単位含有ポリヒドロキシアルカノエートを提供すること。 ポリスチレン換算ゲル浸透クロマトグラフィー測定による重量平均分子量が125万以上であり、重合単位として3-ヒドロキシブチレート単位及び4-ヒドロキシブチレート単位を少なくとも含み、全モノマー単位に対する4-ヒドロキシブチレート単位の割合が14モル%~40モル%である、ポリエステル。
