MODIFIED POLYLACTIC ACID, POLYMERIZED MODIFIED POLYLACTIC ACID, AND METHODS AND APPARATUSES FOR MANUFACTURING THE SAME

摘要

Provided are: a modified polylactic acid that is environmentally friendly, potentially usable as a battery material of a secondary battery or the like, and obtained by chemically derivatizing polylactic acid having an L-lactide structure generated or obtained in the manufacture of polylactic acid; a polymerized modified polylactic acid obtained by further polymerizing this modified polylactic acid; and methods and apparatuses for manufacturing the modified polylactic acid and the polymerized modified polylactic acid. The present invention uses: a modified polylactic acid including a structure represented by general formula (1) below (in formula (1), R1 and R2 are structures containing a metal element and can be the same or different, AA and BB are CC or structures containing a metal element in R3 and R4 and can be the same or different, and R5 is a structure containing a metal element); a polymerized modified polylactic acid; and methods and apparatuses for manufacturing the modified polylactic acid and the polymerized modified polylactic acid.
