Book excerpt: As an ongoing effort to develop structural adhesives for high performance aerospace applications, recent work has focused on phenylethynl terminated imide (PETI) oligomers. The work reported herein involves the synthesis and characterization of a series of phenylethynyl containing oligomers designated as LaRC [trademark]MPEI (Modified Phenylethynyl Terminated Polymide). These oligomers contain mixtures of linear, branched and star-shaped molecules. The fully imidized polymers exhibited minimum melt viscosity as low as 600 poise at 335 degrees C. Ti/Ti lap shear specimens processed at 288 degrees C under 15 psi showed tensile shear strength of approx. 6000 psi and 5200 psi at ambient and 350 degrees F temperatures, respectively. The chemistry and properties of these new MPEIs are presented and compared to an optimized linear PETI, LaRC [trademark]-PETI-5.

Available in PDF, EPUB and Kindle. Book excerpt: This volume chronicles the proceedings of the International Symposium on Polyimides and Other High Temperature Polymers: Synthesis, Characterization and Applications, held in Newark, New Jersey, November 29 – December 1, 1999. Polyimides constitute an important class of materials because of their many desirable traits, for example: low dielectric constant, high breakdown voltage, good planarization, wear resistance, radiation resistance, inertness to solvents, good adhesion properties, good hydrolytic stability, low thermal expansion, long-term stability and excellent mechanical properties.This volume contains a total of 21 papers, all rigorously peer reviewed and revised before inclusion, addressing many aspects and new developments in polyimides and other high temperature polymers. The book is divided into two parts: “Synthesis, Properties and Bulk Characterization†and “ Interfacial or Adhesion Aspects and Applicationsâ€. The topics covered include: structure-property relationships in polyimides; photochemistry and photophysics of polyimides; thermal and UV laser pyrolyses of polyimides; residual stress evaluation in polyimides; synthesis and characterization of a variety of polyimides; high Tg polyimide; fluorinated polyimides; highly oriented polyimide films; high-temperature aromatic copolymer thermosets; shape-memory polymers; polyimides as liquid crystal alignment layers; surface properties of polyimides; metal-containing polyimides for optoelectronic applications; polyimide L-B films; polyimides coated with copper sulfide; carbon fiber/polyimide composites; and simulations of the polyimide/silica interface.This volume offers a wealth of information and represents current commentary on the R&D activity taking place in the technologically highly important field of polyimides and other high temperature polymers and is of value and interest to anyone interested in the fundamental or applied aspects of this topic.
