Poly(4-vinylpyridine), cross-linked is a useful acid scavenger and basic catalyst, replacement for pyridine, enabling simplified workup and product isolation.
Poly(4-vinylpyridine) is useful as an acid scavenger in non-aqueous systems, e.g., in the reaction of acid halides with alcohols or amines, as catalyst in Knoevenagel-type condensations and for the formation of enamines and ketals.
Poly(4-vinylpyridine) (PVP) is an effective matrix for the incorporation of transition-metal ions into polymer electrodes. Cross-linking of PVP was done by heating mixture of linear polymer, triallyl-substituted cross-linking agent and radical initiator. PVP can be cross-linked by necleophilic reaction.
