## Abstract The crystallization of helical nanostructure resulting from the self‐assembly of a chiral diblock copolymer, poly(styrene)‐__b__‐poly(L‐lactide) (PS‐PLLA), is studied. Various crystalline PS‐PLLA nanostructures are obtained by controlling the crystallization temperature of PLLA (__T__~c
