Abstract

A set of linear polymers were synthesized utilizing an electrophilic aromatic substitution reaction (SEAr) between biphenyl and ketone containing electron-withdrawing groups (isatin, IS; N-methylisatin, MeIS; and 4,5-diazafluoren-9-one, DF). Optimization of the polycondensation reaction was made to obtain high molecular weight products when using DF, which has not previously been used for linear polymer synthesis. Due to the absence of chemically labile units, these polymers exhibited excellent chemical and thermal stability. Linear SEAr polymers were blended with porous polymer networks derived from IS and MeIS, and both neat/mixed materials were tested as membranes for gas separation. The gas separation properties of both pristine polymers and mixed matrix membranes were good, showing some polymer membrane CO permeability values higher than 200 barrer.

Abstract

Aromatic copolyimides (PIx) and aromatic-aliphatic copolyimides (PIxEOy) were synthesized by reacting 4,4′-(hexafluoroisopropylidene) diphthalic anhydride (6FDA) with mixtures obtained from 2,2′-bis(4-aminophenyl)hexafluoropropane (6FpDA), 5-diaminobenzoic acid (DABA) and Jeffamine ED-2003 (PEO). The selective thermal removal of PEO from PIxEOy yielded membranes with high thermal stability and good mechanical properties. The presence of carboxylic groups minimized the shrinkage during the cross-linking process. The membranes containing 10 mol% DABA exhibited good O2/N2 and CO2/CH4 separation performance, and resistance to CO2 plasticization. PIx/PIxEOy blends containing less than 10 wt% PEO were prepared. The CO2/CH4 selectivity/permeability balance of cross-linked membranes largely exceeded that of PIx. The results highlight a possible strategy for using analogous cross-linkable polymers exhibiting ethylene oxide moieties as mere additive to prepare high free volume polyimide's membranes, exhibiting enhanced separation properties and high resistance to plasticization.

Abstract

© 2017 American Chemical Society. Membrane gas separation is a mature and expanding technology. However, the availability of better membrane materials would promote faster growth. In this Perspective we analyze the state of the art of membrane materials, including polymers and hybrid materials, as well as the current issues and barriers, and finally, we outline future research directions in membrane science. Development of new membrane materials for large scale separations will rely on a multidisciplinary approach that embraces the broad fields of chemical and materials engineering, polymer science, and materials chemistry.

50. Ursprung und Struktur von Wochenmärkten im Bergland des südwestlichen Sumatra

Author

Galizia, Michele

Abstract

An extensive quantitative, qualitative, archival and literary research on markets was carried out during 1987-1990 by the Institut für Ethnologie, Bern in the district of Rejang-Lebong. Some of the main findings are as follows: The infrastructure built by the Dutch for the exploitation of goldmines and plantations has remained fundamentally unchanged and is, as in the rest of Sumatra, mainly export-oriented. Improvements of such a communication system do not stimulate a diversified system of regional urban centres but are conducive to centralization and monopolization of the economy. This is detrimental to local periodic markets which traditionally combine the functions of bulking, retail and wholesale. On the other hand, in the ever-expanding cash crops areas, new markets based on speculative business practices spring up. Since the villages are concentrated along the main roads, no periodic and hierarchic market-system has evolved as traders prefer to reside in the urban centres and visit markets according to personal schedules. On the other hand, the case of Java illustrates that the administration is pressing for the installment of such a market system., Internationales Asienforum, Bd. 26 Nr. 2 (1995): Internationales Asienforum
