摘要：
A moldable hollow glass filled PBI composition. The composition may be prepared by making a well-mixed slurry of glass microspheres in a solution of PBI in a suitable solvent, and then spinning the slurry through a jet or die under pressure and into a water bath where the particles coagulate. The solvent dissolves in the water, allowing solvent-free PBI-glass composite particles to be isolated.
