Production manner of poly lactic acid stereo complex crystal, poly lactic acid, that compact, Kevlar, madreporic body and ion conductor

摘要

It was superior in heat resistance, it was obtained production manner of the poly lactic acid stereo complex crystal which can produce the poly lactic acid which contains stereo complex crystal with high rate efficiently, with that, the poly lactic acid which includes stereo complex crystal in high content factor, is superior in heat resistance, and the compact which is superior in heat resistance, the Kevlar, the madreporic body and the ion conductor are offered. The process which poly lactic acid or include the D lactic acid unit poly lactic acid and the poly lactic acid which include the L lactic acid unit dissolves the poly lactic acid independent polymer which includes the D lactic acid unit which is the optical isomer which is not included in block copolymer, or the said block copolymer which include with the organicity high-molecular at least 1 genera where structure differs or the poly lactic acid independent polymer which includes the L lactic acid unit in the solvent, prepares the high-molecular mixed solution and the process which removes the solvent in the said high-molecular mixed solution and, it is production manner of the poly lactic acid stereo complex crystal which it possesses.
