Abstract The glass transition temperatures ( T g ) and dynamic mechanical properties of random copolymers of styrene‐4‐vinylpyridine quaternized with iodoalkanes are presented for vinylpyridine contents up to ten percent and pendant alkyl chains up to ten carbons in length. Two linear relationships, between ion content and glass transition temperature and between pendant alkyl chain length and the T g , are observed. An equation is presented that can be used to predict the T g for such copolymers based on their ion contents and alkyl chain lengths.
