Title (EN) LACTIC ACID/OXALATE BLOCK COPOLYMER
(FR) COPOLYMÈRE BLOC ACIDE LACTIQUE/OXALATE
(JA) 乳酸−オキサレートブロック共重合体
Abstract: front page image
(EN)A lactic acid/oxalate block copolymer having toughness superior to that of polylactic acid. There are provided a lactic acid/oxalate block copolymer (1) composed of polylactic acid blocks and polyoxalate blocks which have respective number average molecular weights ranging from 2000 to 50,000; a crystalline lactic acid/oxalate block copolymer (2) according to the copolymer (1) wherein the polylactic acid blocks and polyoxalate blocks have respective average numbers of blocks ranging from 0.1 to 9; etc.
(FR)La présente invention décrit un copolymère bloc acide lactique/oxalate de résistance mécanique supérieure à celle de l'acide polylactique. La présente invention décrit notamment un copolymère bloc acide lactique/oxalate (1) composé de blocs acide polylactique et de blocs polyoxalate dont les masses moléculaires moyennes en nombre respectives sont comprises entre 2000 et 50 000 ; un copolymère bloc cristallin acide lactique/oxalate (2) selon le copolymère (1) où les nombres de blocs moyens des blocs acide polylactique et des blocs polyoxalate sont compris entre 0,1 et 9 ; etc.
(JA)本発明は、ポリ乳酸に比べてタフネスがある乳酸−オキサレート共重合体を提供することを課題とし、1)ポリ乳酸ブロックとポリオキサレートブロックから構成され、ポリ乳酸ブロック及びポリオキサレートブロックの数平均分子量がそれぞれ2000~50000の範囲である乳酸−オキサレートブロック共重合体、2)ポリ乳酸ブロック及びポリオキサレートブロックの平均ブロック数がそれぞれ0.1~9の範囲である、前記1)の結晶性乳酸−オキサレートブロック共重合体などを提供する。
