The Use, Design, Synthesis, and Properties of High Performance/High Temperature Polymers: An Overview

Abstract

An overview of the definition and development of, factors that contribute to, applications and markets for and the design of high performance/high temperature polymers is presented. Of the many families of high performance/high temperature polymers known, the most popular families consisting of polyimides, polyarylene ethers and phenylethynyl-terninated oligomers are used to demonstrate the basic principles in polymer development. Chemical structure/property relationships are used to show how polymers can be designed with a unique combination of properties. The estimated worldwide market for high temperature polymers in 2000 was 206,700,000 kgs constituting $4.36B with polyimides comprising 3,982,000 kgs or $1 .07B (24% of the dollar value). With an improvement in the world economy, this market is predicted to grow substantially

Formation and thermal stability of BMI-based interpenetrating polymers for gas separation membranes

“…The decrease in these temperatures for complete degradation was due to the lower stability of polymerized BMI and perhaps to the relatively low molecular weight of the BMI resin. The influence of molecular weight and its distribution on thermal stability of polymers was illustrated elsewhere [39]. On the other hand, it was interesting to see that PEI-BMI-EtOH-S membrane had the same residue of 19% at 800 • C as the one without BMI although the polymerization time of BMI was shorter than that for PEI-BMI-EtOH-L membrane.…”

Study on Synthesis of PAEKs Containing Triazole Units through Click Reaction and Their Properties

“…[1][2][3][4] These advanced materials have been receiving considerable attention for past decades due to their successful applications in aerospace, automobile, electronics and other high technology fields, 5 such as high-temperature coating, toughening agents, ultrafiltration membranes and ionic exchange membrane after carrying ionic exchange groups for fuel cell and vanadium redox battery so on.…”

Synthesis and characterization of phenylethynylcarbonyl terminated novel thermosetting imide compound

“…However, their rigid polymer backbones and the strong chain interactions result in poor solubility and high softening or melting temperature for most of aromatic polyimides, which limit their use for commercial purposes. Therefore, for molding compounds or matrix resins of fiber reinforced plastics, many addition-type (thermosetting) polyimides (imide oligomers terminated with reactive groups) have been developed [1][2]. These imide oligomers terminated with reactive groups could be thermally cured at high temperatures providing good processibility.…”
