520 $a Several series of liquid crystalline polymers comprised of various chain architectures have been designed, synthesized and characterized to examine the influence of chain architecture on polymer chain dynamics.
520 $a Two liquid crystalline (LC) side-group poly(methacrylates) were synthesized, and their melt dynamics were compared with each other and a third, main-chain side-group combined LC polymer. A new route was employed to synthesize the side-group polymers, which were chosen to study the melt dynamics of LC polymers with different side-group packing. The main-chain side-group poly(malonate) had a similar side-group but possessed a more complex phase behavior. Side-group interdigitation appears to lead to much slower diffusion in the direction perpendicular to the smectic layer planes.
520 $a The influence of branching on mesomorphic behavior and defect structure was examined by comparing two families of linear and 3-armed star oligomers based on different mesogens. The use of AB monomers allowed the synthesis of various molecular weight AB oligomers with exactly one functional group, which were then cyclotrimerized into single-branched, or 3-armed star systems. The presence of a branch point was found to have a drastic affect on the ability of the molecules to form mesophases, and for the mesophases to undergo defect annihilation.
520 $a Three block copolymers were synthesized through the coupling of $\ alpha $ or $\ alpha,\omega $ end-functionalized LC poly(ethers) with monodisperse monocarboxylic acid-terminated poly(styrene) or poly(ethylene) homopolymers. This family of polydisperse block copolymers was examined in an effort to evaluate the synthetic route and to study the interaction between the two chemically different blocks.
520 $a Finally, several series of semi-rigid main-chain polymers were prepared to examine the influence of side groups, hydrogen bonding, stiffness and mesogen choice on polymer properties. Based on the choice of mesogen, hydrogen bonding was found to either inhibit or promote mesomorphism. Increasing "spacer" stiffness led to shorter chain lengths, decreased solubility and increased transition temperatures.
