Claims22
A composite block article comprising:
- a) 1 to 15 weight percent of a polyamide binder, and
- b) 85 to 99 weight percent of interactive particles having an average particle diameter of from 0.1 to 3,000 microns, the weight percent based on the total of polyamide and interactive particles,
- wherein said polyamide has an average particle size of between 1 and 50 microns, wherein the particle size distribution is such that 80% of the particles have a size between 0.5 times the average particle size and 2 (two) times the average particle size and wherein said polyamide is porous as measured by having a specific surface area of greater than 0.5 m2/g.
The process of claim 21, wherein said fluid is selected from the group consisting of aqueous liquid, organic solvents, pharmaceutical or biological preparations, hydrocarbon base fluids, or blends thereof.
