✦ Synopsis

Grafting of acrylic acid on polytetrafluoroethylene has been performed using films of the polymer gamma-irradiated in air and then treated with aqueous acrylic acid. It is concluded that the initiating centres are peroxides POOP'~ where P' is a small perfluorinated fragment, and also trapped peroxy radicals PO~ which undergo deoxygenation. Homopolymerizatien is suppressed by polymerization inhibitors.

Decrease of the intensity of excimer fluorescence during the photo-oxidation of polystyrene indicates that energy transfer occurs from excited phenyl chromophores to oxidation products. Among these, hydroperoxide groups are prominent because, after acting as energy acceptors, they decompose efficien
