Abstract
The CECEC pentablock, CEC triblock and CE diblock copolymers were prepared by a combination of anionic polymerization and catalytic hydrogenation. The tensile testing of the extruded materials was performed at room temperature using a MINIMAT tensile tester operated at a cross-head speed of 5 mm min -1. Characterization results for these polymers were also presented. The CECEC/DOP blends were prepared by dissolution of both components in benzene followed by freezing in liquid nitrogen. The two-dimensional SAXS patterns obtained from undrawn CECEC extrudes reveal an isotropic arrangement of lamellae. The addition of DOP reduces the order-disorder transition temperature as indicated by DMS and small-angle X-ray scattering (SAXS) measurements.
