Abstract
Although radiation grafting of styrene to poly(acrylamide) was found to be inefficient in aqueous micellar media, however, hexadecylpyridinium chloride micelles provided a measure of control over the grafted styrene side-chain lengths. Fluorescence measurements indicated that the side chains ranged from 24 to 52 units and gave rise to hydrophobic domains in aqueous copolymer solutions. Fluorescence quenching was monitored to show that the copolymers isolate and screen hydrophobic guest molecules from the aqueous phase. Hydrolysis of the poly(acrylamide) backbone resulted in no significant change in the characteristics of the hydrophobic domains
