Three different gel-filled microporous poly(propylene) hollow fiber (HF) membranes were prepared by the incorporation of poly(4-vinylpyridinium salt) gels into the fiber walls. The gels were anchored in the pores of the membrane by cross-linking poly(4-vinylpyridine) with α,α′-dichloro-p-xylene, followed by quaternization using benzyl bromide. Different distributions of the gel were achieved by varying...
The ultra-low pressure water softening properties of a series of novel membranes containing cross-linked poly(4-vinylpyridinium) salts incorporated into the pores of polyethylene or polypropylene microfiltration membranes have been examined. It has been shown that these membranes exhibit excellent separation properties with high permeabilities at low trans-membrane pressures. The separation mechanism...
