The miscibility of poly(1‐vinylimidazole) (PVI) with some hydroxyl‐ and carboxyl‐containing polymers was studied. Each of the binary blends or complexes of PVI with poly( p ‐vinylphenol) (PVPh), poly(2‐hydroxypropyl methacrylate) (PHPMA) and poly(acrylic acid) (PAA) showed a single glass transition temperature ( T g ), indicating miscibility. However, PVI is immiscible with poly(styrene‐ co ‐allyl alcohol) (SAA) and poly(hydroxyether of bisphenol‐A) (Phenoxy) as shown by the appearance of two T g 's in each of the blends. Based on the frequency shifts of the hydroxyl band of the hydroxyl‐containing polymers, the intensities of hydrogen bonding interactions between PVI and hydroxyl‐containing polymers are in the order PVPh > PHPMA > SAA and Phenoxy. PVI interacts with PAA via ionic interaction.
