"The goals of this research are the synthesis of novel three-component polyamic acids and polyimides, and corresponding pendant polymers where nonlinear optical (NLO) "chromophores" have been attached. Synthesis of a corresponding guest molecule is also sought to facilitate structural and NLO property comparisons. All synthesized materials were characterized with TLC, NMR, FTIR, and UV-VIS. Polymers were characterized by TGA. The average molecular weight of one polymer was determined by ebulliometry and dilute solution viscosity. Starting materials were chosen to increase the flexibility, lower hydrophilicity, and achieve colorlessness of the polymer backbone by incorporating additional C-F bonds between the aromatic rings of the diamines and dianhydrides ..."--Abstract.

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.

The last twenty years or so have seen a flurry of activity in the synthesis of new polymer systems. This interest has developed largely as a result of the increased need for advanced materials. Despite the emergence of a number of outstanding polymers, it is the polyimides that have captured the imagination of scientists and engineers alike as materials that offer outstanding promise for the high technology applic ations of the future. The reputation of the polyimide has been established on the bases of outstanding thermal stability, excellent mechanical properties and the ability to be fabricated into useful articles. Polyimides offer a versatility unparalleled in most other classes of macromolecules. Polymers can be prepared from a variety of starting materials, by a variety of synthetic routes. They can be tailor-made to suit specific applications. By judicious choice of starting materials, polymers can be made that offer variations in such properties as glass transition tempera ture, oxidative stability, toughness, adhesion, and permeability. It is this versatility that has led to the use of polyimides in a wide variety of applications. The electronics industry makes extensive use of poly imide films in, ior example, semiconductor applications. The leading polymer matrices for high temperature advanced composites are polyimides. High temperature adhesive systems for the bonding of metals or composites are often based on polyimides. In addition, polyimides are now finding use as fibres, foams, sealents and even membranes for the low energy separation of industrial gases.
