High performance mixed bisimide resins and composites based thereon [PDF]
, 1986 Mixtures of bismaleimide/biscitraconirnide resins produces materials which have better handling, processing or mechanical and thermal properties, particularly in graphite composites, than materials made with the individual resins. The mechanical strength

The magnetic and electronic structure of vanadyl pyrophosphate from density functional theory [PDF]
, 2011 We have studied the magnetic structure of the high symmetry vanadyl pyrophosphate ((VO)_(2)P_(2)O)7, VOPO), focusing on the spin exchange couplings, using density functional theory (B3LYP) with the full three-dimensional periodicity. VOPO involves four

Crystal structure of 2,3-dimethylmaleic anhydride: continuous chains of electrostatic attraction
Acta Crystallographica Section E: Crystallographic Communications, 2015 In the crystal structure of 2,3-dimethylmaleic anhydride, C6H6O3, the closest non-bonding intermolecular distances, between the carbonyl C and O atoms of neighboring molecules, were measured as 2.9054 (11) and 3.0509 (11) Å, which are well below the sum ...

Fire and heat resistant laminating resins based on maleimido substituted aromatic cyclotriphosphazene polymer [PDF]
, 1987 4-Aminophenoxy cyclotriphosphazenes are reacted with maleic anhydride to produce maleamic acids which are converted to the maleimides. The maleimides are polymerized. By selection of starting materials (e.g., hexakis amino or trisaminophenoxy trisphenoxy

Addition polyimide end cap study [PDF]
The characterization of addition polyimides with various end caps for adhesive applications at 120-250 C environments is discussed. Oligometric polyimides were prepared from 3,3',4,4'-benzophenone tetracarboxylic dianhydride and 3,3'-methylenedianiline ...

Preparation of Poly(oxybutyleneoxymaleoyl) Catalyzed by a Proton Exchanged Montmorillonite Clay
Molecules, 2004 The polycondensation of tetrahydrofuran with maleic anhydride catalyzed byMaghnite-H+ (Mag-H) was investigated. Maghnite is a montmorillonite sheet silicateclay that is exchanged with protons to produce Maghnite-H [1]. It was found that thepolymerization

Telechelic polyisobutylene with unsaturated end groups and with anhydride end groups [PDF]
, 1993 Anhydride terminated polyisobutylene (PIB) oligomers were synthesized in a one- or two-step process from chlorine terminated oligomers. In the one-step process, chlorine functional oligomers were just heated in the presence of maleic anhydride (MA) for ...
