Abstract
The crystallization-induced deformation of spherical microdomains in block copolymer blends consisting of a soft amorphous phase was presented. The crystallization of polyethylene oxide (PEO) blocks within the spherical microdomains were induced at the temperatures above T g of polybutadiene (PB) and the domains were dispersed in a soft matrix during crystallization. Results showed that the spherical microdomains present in the melt state of a PEO-b-PB/PB blend system were not preserved upon crystallization.
