Abstract

Various crystalline textures have been identified in a crystallizable block copolymer system, polystyrene-block-[syndiotactic poly(propylene)] (PS-sPP), having a glass-transition temperature of PS (T_g,PS) located in the midst of the sPP crystallization window. A confined morphology for the crystallization of sPP was observed while the crystallization temperature of sPP (F_c,sPP) was less than T_g,PS. A further increase in T_c,sPP could lead to a breakout in nanostructure. This study revealed the T_g effect on crystal-lization-induced morphological changes of block copolymers from confinement to breakout.
