Poly(mandelic acid) (PMA) is structurally similar to polystyrene (PS) having a high glass transition temperature (Tg), and thus is stable even at a relatively high temperature. In addition, PMA having a stereoregularity has crystallinity. In the case of crystalline polymer, a controlled low-dimensional structure that may not be seen in the self-assembly behavior of an amorphous polymer can be observed. Herein, we report the synthesis of block copolymers composed of discrete stereoregular poly(mandelic acid) and poly(ethylene glycol). Furthermore, We can compare the CDSA behaviors according to the controlled stereoregularity and the chain length of poly(mandelic acid). It is expected that this work allow us to understand the crystallization of PMAs and enable more precise polymer nanostructure design.
