Abstract

The focus of the research presented in this thesis deals with the synthesis and development of functionalized polymers using ring-opening metathesis polymerization (ROMP). The approach taken in developing the polymers presented within, feature the careful design and synthesis of a number of functionalized and unique monomers. A basic history and overview of olefin metathesis and polymer science is given in Chapter 1. Chapters 2 and 3 describe the development of controlled polymer architectures for use as barrier materials. This work was done in collaboration with Kuraray, Inc, which is a major manufacturer of commercial barrier materials. Also the structure-property relationships of these materials were studied to better understand how polymer architecture affects polymer properties. Chapter 4 discusses the controlled living ROMP of highly strained trans-cyclooctene. The knowledge and understanding of solvent effects during ROMP was also explored as a means to attenuate the rate of propagation during ROMP. Block copolymers containing polynorbornene and PCO were also synthesized and hydrogenated to form block copolymers containing blocks of linear, narrowly dispersed polyethylene. Chapter 5 describes the development of photodegradable polymer. By incorporating photodegradable links into a polymer chain, using ROMP, the polymer chain may be degraded upon irradiation with light.
