The effect of solvent on the formation of excimer from copolymers of 2‐(1‐naphthylacetyl)ethylacrylate (NAEA) with both acrylamide (AM) and N ‐vinyl pyrollidone (VP) in dilute solution was investigated. A minimum in excimer intensity was observed for each of the copolymers at approximately 2.20 × 10 4 (J/m 3 ) 0.5 . It is suggested that the relatively high content of NAEA in the copolymers (between 30 and 60%) governs the overall solubility parameter of the polymer.
