Poly(o-butyrylstyrene) (POBS) was exposed in the form of thin films to long-wave UV radiation (ha300 nm) under high vacunm at 25 ): 1 "C. Ethylene was the principal low-molecular-weight product, but much smaller amounts of CO, methane, ethane and propane were also formed. Quantum yields for gaseous
