Abstract:
A blow molding having capacity of at least 250 ml, having a shell which is composed of impact-resistant polystyrene and which is produced via injection stretch blow molding where an average aspect ratio of rubber particles derived from longitudinal section and an average aspect ratio of rubber particles derived from cross section measured in transmission electron micrographs is greater than 4 respectively, and a biaxial orientation of the rubber particles, given by the ratio of the aspect ratio derived from cross section to the aspect ratio derived from longitudinal section is smaller than 3.
