Spatial Organization of Polymer Chains in a Crystallizable Diblock Polyethylene and Polystyrene

Abstract

A diblock copolymer containing polystyrene and linear polyethylene was synthesized using anionic-to-Ziegler/Natta transformation reaction. Combined evidence from 2-D small angle X-ray scattering and wide angle x-ray pole figure analysis showed conclusively that the polyethylene chains crystallize within the heterogeneous structure in a manner which leaves the polyethylene chains (c- axis) parallel to the lamellar surfaces.
