Vacuum UV radiation

The correlation is not perfect, but the limitations do not seriously detract from the usefulness of the method. The technique is not limited to vacuum UV radiation. Higher energy radiation can also be used.

When X-rays are used rather than vacuum UV radiation, electrons are emitted from inner orbitals, and the spectrum obtained reflects this. These spectra also give much scope as an analytical technique.

The cation is more reactive than the free radical, thereby dominating the initiation reaction. Radical cations can also he formed by high energy electrons, vacuum UV radiation, high intensity electric fields, or anodic oxidation of the monomer. Nuclear chemical initiation involves the use of tritium this method produced very high molecular weight polyisobutylenes and polystyrenes (65).
