“…In crystalline short-chain n-alkanes from butane to octane, between 30% -2q), from which q, the average number of cross-links per initial molecule, is obtained. and 50% of dimerization was found to occur immediately, possibly by a non-radical mechanism, at temperatures below 140K [39,103]. This has been deduced from experiments where the irradiated crystals were dissolved in a radical scavenger at temperatures sufficiently low to prevent any combination of trapped radicals before dissolution was completed.…”

The effect of high-energy radiation on n-alkanes and polyethylene (PE) are reviewed. The article includes a description of (a) primary radiation events, formation, spatial distribution and decay of free radicals and radical migration mechanisms, (b) formation of cross-lin ks and other sta ble products, (c) the effects of crystal linity, crystalline modifications and morphology on radiation cross-linking, and (d) radiation-induced changes in the crystal lattice and the destruction of crystallinity at high irradiation doses.An attempt is made to bring together conflicting views on various unsolved problems of the radiation physics and chemistry of these important and much studied substances. Long-chain paraffins are given considerable attention since their radiation behaviour often provides a link between that of PE and its short-chain analogues.
