Synthesis and Properties of Model Graft and Flexible/Semi-Rigid Block Copolymers

摘要

We have developed synthetic schemes which allow the synthesis of graft copolymers with precisely controlled architectures and narrow molecular weight distributions. The study of the properties of these materials, through collaborations with Professor Samuel Gido (Univ. of Massachusetts) and others, has led to an enhanced understanding of the effect of branching on block copolymer morphology. Flexible/semi-rigid block copolymers have also been synthesized and studied in order to explore effects of chain stiffness on block copolymers. The results from these studies are summarized herein; details are given in the fifteen refereed publications that have been produced during this project.
