POLYLACTIC ACID, BINDER COMPOSITION, AND SINTERING PASTE
To provide a polylactic acid for sintering paste that can be dissolved in a solvent without visible undissolved residues, has effective rheological properties when mixed with the solvent, and also has excellent sinterability.SOLUTION: A polylactic acid includes an L-isomer component and a D-isomer component. When the total of the L-isomer and D-isomer components in the polylactic acid is defined as 100 mass%, the content ratio of the L-isomer component, which is termed the L-lactic acid ratio, or the content ratio of the D-isomer component, which is termed the D-lactic acid ratio, ranges from 60 to 93 mass%.SELECTED DRAWING: None
【課題】溶剤に視認可能な溶け残りなく溶解可能であって、溶剤と混合した際、有効なレオロジー特性を有し、優れた焼成性を併せ持つ、焼成用ペースト用のポリ乳酸を提供する。【解決手段】本発明によれば、Ｌ体成分及びＤ体成分を含むポリ乳酸であって、ポリ乳酸に含まれるＬ体成分及びＤ体成分の合計を１００質量％としたときの、Ｌ体成分の含有比率であるＬ－乳酸比、又はＤ体成分の含有比率であるＤ－乳酸比が６０～９３質量％である、焼成用ペースト用のポリ乳酸が提供される。【選択図】なし
