Presentation Transcript

  1. Materials World Network - Renewable Resource Thermotropic PolyesterMichael Jaffe, New Jersey Institute of Technology, DMR 0908583 Isosorbide/Isoidide Based Mesogenic Monomers Intellectual Merit: The Inter-American Materials Collaboration between NJIT and Universidad Nacional Autónoma de México (UNAM) is developing new, sustainable backbone chem-istries for thermotropic polyesters. Our goals are: • Synthesize new mesogenic monomers and polymers based on isosorbide/isoidide • Mesogenic monomers using isosorbide as a building block with known mesogenic moieties like biphenyl and naphthalene have been synthesized. • Homopolymerization of these monomers results in new, sustainable, high performance polyesters with Tg>150°C and Tm≥290°C • These materials are being evaluated as p- phenylene polyester (LCP) “backbone disrupters” • Increase the understanding of the relationships between polymer backbone chemistry, (liquid crystal) LC phase creation and LCP performance DSC: Isosorbide-2-[4(4’-carboxyphenyl)phenyl]ether DSC: Poly-Isoidide-2-[4(4’-carboxyphenyl)phenyl]ether POM Images of Isosorbide-2-[4-(4’-carboxyphenyl)phenyl]ether
