Spontaneous Polymerization of 4-Vinyl Pyridine for Hollow Fiber Ion Exchangers
It was previously shown1 that 4-vinyl pyridine (4-VP), polymerized spontaneously in presence of alkyl halides. The growing active species in this polymerization system exhibited high specificity. It was reacting only with monomeric vinyl pyridinium salts and not with other vinyl monomers including 4-VP. Therefore, in presence of excess of 4-VP, the polymerization was arrested after the alkyl halide was used up in the quaternization reaction. It was also observed that free radical inhibitors had no effect on the polymerization rate.
