Al~tracl--The efficiency of triplet energy transfer from the benzophenone group to naphthalene has been studied in a series of copolymers styrene-vinylbenzophenone, either as films or in glassy solutions at 77 K. Energy migration has been shown to be efficient in both cases. For a given copolymer, H
