Polylactic acid derivative, method for producing the same, and polylactic acid-based stereocomplex

摘要

The polylactic acid derivative according to the present invention is represented by the following general formula (1) or general formula (2). [Chemical 1] In general formula (1), one of X1 to X5 is an aldehyde group, one of the remaining four is an alkoxy group, and the remaining three are hydrogen atoms. A polylactic acid derivative represented by the following general formula (2). [Chemical formula 2] In general formula (2), one of R1 to R3 is any one of a chlorine atom, a fluorine atom, an aldehyde group, an alkoxy group, an alkyl group, and an ester, and the remaining two are a chlorine atom, a fluorine atom, an aldehyde group, One of an alkoxy group, an alkyl group, an ester, and a hydrogen atom.
