摘要:Isotactic poly ((R)-lactic acid) or isotactic poly (S)-lactic acid are respectively prepared from (R,R)-lactide and (S,S)-lactide using a catalyst which has a zinc center or a magnesium center and two ligands where one of the ligands is a propagating group and the other of the ligands is not a propagating group. Heterotactic poly(lactic acid) is prepared from rac-lactide using a catalyst which has a zinc center and two ligands where one of the ligands is a propagating group and the other of the ligands is not a propagating group; heterotactic poly(lactic acid) is a novel composition. The catalyst with a magnesium center is a novel catalyst. Syndiotactic poly(lactic acid) is prepared from meso-lactide using a syndiotactic poly(lactic acid) effecting catalyst which has a zinc center and two ligands where one of the ligands is a propagating group and the other of the ligands is not a propagating group and the preferred catalyst contains as the ligand which is not a propagating group diiminate substituted with isopropyl substituted phenyl and the propagating group is isopropoxide. Atactic poly(lactic acid) of polydispersity ranging from 1.15 to 1.40 is prepared in less than 10 minutes by polymerizing rac-lactide in the presence of C 1 -C 4 alcohol and a catalyst with a magnesium center and two ligands where one of the ligands is a propagating group and the other of the ligands is not a propagating group.

摘要:Methods for forming magnesium batteries include improved processes for synthesizing magnesium electrolytes. The magnesium electrolytes include boron cluster anions, and the improved methods are solid phase or solution phase reactions that yield the desired magnesium boron cluster electrolytes from inexpensive, commercially available starting materials in a single step with relatively high purity.
