Abstract

A novel method has been developed for the synthesis of poly(arylene ether ether sulfides). Amorphous poly(arylene ether ether sulfoxides) serve as amorphous precursors for these semi-crystalline poly(arylene ether ether sulfides). The sulfoxide polymers have been prepared using conventional aromatic nucleophilic substitution reactions between difluorodiphenyl sulfoxide and diphenols. It has been demonstrated that controlled molecular weight sulfoxide polymers can be made using a suitable non-reactive endcapping reagent. Rapid reduction of the sulfoxide polymers in a suitable solvent with oxalyl chloride and tetrabutylammonium iodide yielded micron size particles of poly(arylene ether ether sulfides). Quantitative conversion and retension of molecular weight upon reduction has also been demonstrated. Synthesis and structural and thermal characterization of this new class of materials will be discussed.

Crystallization kinetics of poly(arylene ether ether sulfides): Dual spherulitic morphology

Conference Srinivas, S; Wilkes, G; Babu, J

This study is focused on the crystallization studies on a series of novel poly(arylene ether ether sulfides) developed at VPI. Preliminary growth rate investigations have been carried out on these novel poly(arylene ether ether sulfide) polymers as a function of molecular weight. During the course of these investigations, two distinct populations of spherulites were observed at all temperatures. These spherulites referred to as Type I and Type II spherulites exhibited very different morphologies and distinctly different growth rates. Preliminary investigations show that the different spherulites could be the result of pre shearing the sample prior to crystallization. Detailed morphological resultsmore »« less
Controlled molecular weight poly(arylene ether benzimidazole)s endcapped with benzimidazole and acetylene groups

Conference Smith, Jr, J; Connell, J; Hergenrother, P

As a continuation of work on poly(arylene ether benzimidazole)s (PAEBIs), a series of controlled molecular weight polymers endcapped with benzimidazole, ethynyl, and phenylethynyl groups were prepared at stoichiometric imbalances of 7 and 10 mole percent and characterized. Earlier work with benzimidazole endcapped PAEBIs prepared at stoichiometric imbalances as high as 7 mole percent has shown very good retention of thin film properties up to 232{degrees}C. Ethynyl and phenylethynyl endcapped PAEBIs, air cured to 330{degrees}C, exhibited increases in Tgs of {approximately}20-30{degrees}C with respect to benzimidazole endcapped PAEBIs. Thin film properties for the ethynyl and phenylethynyl endcapped PAEBIs were similar to benzimidazolemore »« less
High Temperature, Low Relative Humidity, Polymer-type Membranes Based on Disulfonated Poly(arylene ether) Block and Random Copolymers Optionally Incorporating Protonic Conducting Layered Water insoluble Zirconium Fillers

Technical Report McGrath, James; Baird, Donald

Our research group has been engaged in the past few years in the synthesis of biphenol based partially disulfonated poly(arylene ether sulfone) random copolymers as potential PEMs. This series of polymers are named as BPSH-xx, where BP stands for biphenol, S stands for sulfonated, H stands for acidified and xx represents the degree of disulfonation. All of these sulfonated copolymers phase separate to form nano scale hydrophilic and hydrophobic morphological domains. The hydrophilic phase containing the sulfonic acid moieties causes the copolymer to absorb water. Water confined in hydrophilic pores in concert with the sulfonic acid groups serve the criticalmore »« less

High temperature fuel cell membranes based on poly(arylene ether)s containing benzimidazole groups

Conference Kim, Dae; Kim, Yu; Lee, Kwan; ...

Development of new high-performance polymer membranes that retain their proton conductivity under low humidity conditions is one of the most critical requirements to commercialize PEMFC systems. Current sulfonated proton exchange membranes acquire proton conductivity by water that solvates ion and carries proton. Consequently, a loss of water under low RH conditions immediately results in a loss of proton conductivity. One approach to maintain proton conductivity under low RH conditions is to replace water with a less volatile proton solvent. Kreuer has pointed out the possibility to develop fully polymeric proton-conducting membranes based on nitrogen-containing heterocycles such as imidazole, benzimidazole, andmore »« less

Synthesis and thermomechanical characteristics of zwitterionic poly(arylene ether sulfone) copolymers

Journal Article Yang, Yi; Behbahani, Hoda; Morgan, Brian; ... - Polymer

Charge-containing polymeric materials have been widely studied for a range of applications. The fundamental relationships between the charge species, charge density, and the microscale morphology of charge-containing polymers are critical for defining the application in which they may be used. In this work, a series of thermoplastic poly(arylene ether sulfone) (PAES) copolymers with controllable sulfobetaine charge contents (0~100 mol%) and high molecular weights (Mw ~ 65 kDa) were prepared. All the zwitterionic PAESs synthesized showed thermal stability up to 250 °C. DSC and tensile tests showed a decreased T_g and mechanical strength with the incorporation of increasing charge density, whichmore »« less
