- Abstract
- A vinyl terminated polystyrylpyridine (VPSP) resin was blended with a bismaleimide resin at a ratio of 3 to 7 by weight to produce fire resistant and thermally stable resin blends. The VPSP resin was characterized by Infrared Spectrum (IR), Proton NMR, gel permeation chromatography (GPC), differential scanning calorimetry (DSC), solubility and volatile content. The VPSP-bismaleimide blends were characterized by determining their melting point and viscosity of the blend. The thermal performance of the neat resin blend is described in terms of the anaerobic char yield. Graphite composites were prepared with this blend and their excellent fire resistance and thermal stability was demonstrated by the low mass loss when exposed to a radiant heat source, and the low smoke evolution.
